He had read 12 pages on the first day, 6 more pages on the next day, and 48 pages on the last day. How many days had he read?
After reading 12 pages on the first day, he read 6 more pages every day than the previous day. On the last day, he read 48 pages. How many days did he read in total? He had read $12+12 + 12 + 12 + 12 +12+6+48$in total. Reading 6 more pages a day than the day before, so obviously in the first week, I read $12+12 + 12 + 12 + 12 +12+6+12=55$days. In the second week, he read $12+12 + 12 + 12 + 12 +12+6+12+12=63$days. By analogy, we can know that the total amount of reading before the end of the book is $55+63+70+73+80+86+98+48=695$days. Therefore, he read for a total of seven days.
When Xiao Li read a novel, she would read 74 pages on the first day, 82 pages on the second day, 71 pages on the third day, 63 pages on the fourth day, and more pages on the fifth day than this…
The number of pages read on the fifth day was the number of pages read on the first day plus the number of pages read on the fourth day, which was 74 + 82 = 156 pages. Because the number of pages read on the fifth day was more than the sum of the previous four days, 156 > 4 × 71 + 3 × 63 + 2 × 82 + 1 × 74. Therefore, the answer was that Xiao Li read page 156 on the fifth day.
If you read 20% of the book on the first day, 25% of the total pages on the second day, and there are 110 pages left, how many pages are there in the book? stated
Let the total number of pages in this book be x pages. Reading 20% of the book on the first day meant reading 20% * x pages, which was 02x pages. The next day, he read 25% of the total number of pages, which meant that he read 25% * x pages, which was 025x pages. There were 110 pages left. According to the above calculation, the equation can be listed: 02x + 025x + 110 = x Solve this equation: 3x = 110 x = 33 Therefore, the total number of pages in this book was 33.
18 pages a day, 14 days to read and play. If you finish reading it five days in advance, how many pages should you read every day?
If you read 18 pages a day, it would take you 14 days to finish it. If you want to finish the book 5 days earlier, you need to shorten the number of days to 10 days. 5 days earlier is equivalent to reading 18 pages less per day, so you need to read 24 pages per day (14 days-5 days =10 days).
For an extra-cursory book, after reading 24 pages on the first day, he would read 3 more pages each day than the previous day. On the last day, he would read 36 pages.
The number of pages of this extra-cursory book should be an increasing number, so we can list its approximate values as follows: 24 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 101 103 105 107 109 111 113 115 117 119 121 123 125 127 129 131 133 135 137 139 141 143 145 147 149 151 153 155 157 159 161 163 165 167 169 171 173 175 177 179 181 183 185 187 189 191 193 195 197 199 201 203 205 207 209 211 213 215 217 219 221 223 225 227 229 231 233 235 237 239 241 243 245 247 249 251 253 255 257 259 261 263 265 267 269 271 273 275 277 279 281 283 285 287 289 291 293 295 297 299 301 303 305 307 309 311 313 315 317 319 321 323 325 327 329 331 333 335 337 339 341 343 345 347 349 351 353 355 357 359 361 363 365 367 369 371 373 375 377 379 381 383 385 387 389 391 393 395 397 399 401 403 405 407 409 411 413 415 417 419 421 423 425 427 429 431 433 435 437 439 441 443 445 447 449 451 453 455 457 459 461 463 465 467 469 471 473 475 477 479 481 483 485 487 489 491 493 495 497 499 501 503 505 507 509 511 513 515 517 519 521 523 525 527 529 531 533 535 537 539 541 543 545 547 549 551 553 555 557 559 561 563 565 567 569 571 573 575 577 579 581 583 585 587 589 591 593 595 597 599 601 603 605 607 609 611 613 615 617 619 621 623 625 627 629 631 633 635 637 639 641 643 645 647 649 651 653 655 657 659 661 663 665 667 669 671 673 675 677 679 681 683 685 687 689 691 693 695 697 699 701 703 705 707 709 711 713 715 717 719 721 723 725 727 729 731 733 735 737 739 741 743 745 747 749 751 753 755 757 759 761 763 765 767 769 771 773 775 777 779 781 783 785 787 789 791 793 795 797 799 801 803 805 807 809 811 813 815 817
If Xiao Ming read 35 pages a day, he would finish the book one day later than the stipulated date. If he read 40 pages a day, he would have to read 5 pages less on the last day.
Xiaoming reads a novel. If he reads 35 pages a day, he will finish the book one day later than the stipulated date. If he reads 40 pages a day, he will read 5 pages less on the last day. Based on this information, we can formulate the following equation: Let the total number of pages in the novel be x Xiaoming reads x/35 days, that is, he reads x/35 pages every day. Because Xiao Ming needed to finish reading the entire book, he needed to meet the following two conditions: Xiaoming finished reading the novel before the stipulated date 2 Xiao Ming reads 35 pages a day, so the total number of pages read is 35x/12 days Therefore, we can write the following equation: x/35 = (x/12) - 1 Solve the equation: x = 35x/12 + 1 = 40 Therefore, Xiao Ming needed to read 40 pages to finish the novel. He needed to read 40/35=8/17 days before the specified date. However, because reading 40 pages a day is slower than reading 35 pages, the actual time he needs will be longer than 8/17 days, that is, he will need 16/17 days to finish reading the novel.
Fang Fang read a long novel. On the first day, she read 40 pages. From the second day onwards, the number of pages she read every day was five more than the previous day. On the last day, she read 80 pages.
Fang Fang reads a long novel. She reads 40 pages on the first day, 5 pages more on the second day, and 80 pages on the last day. So she reads $40+40 + 40 + 40 +40+5+80=225$pages. Fang Fang read 40 pages on the first day and 5 more pages on the second day, which was 45 pages. The remaining pages were 40+45=85 pages. Because the number of pages she read every day was 5 pages more than the previous day, Fang Fang needed to read a total of ${85+85}{2}=50$days. Because Fangfang had read 80 pages on the last day, she needed to read 80+5+80=130 pages, so the remaining pages were 50-130=-80 pages. This result was a negative number that did not conform to the actual situation. Therefore, Fangfang did not finish reading the novel.
Ding Ding read a book. On the first day, he would read 15 pages. After that, he would read five more pages every day than the previous day. After five days, he would finish reading. How many pages does this book have?
Assuming that the book has x pages: 15 pages on the first day, so there are 15 pages in the book From now on, I'll read five more pages every day than the day before, so after five days, I'll read (15+5)×5=125 pages, plus the 15 pages I've already read before, that's a total of 270 pages Therefore, the book had a total of 270 pages.
Little Ming read a book. He read 15 pages in the first 4 days and 6 pages a day in the next 5 days. How many pages did he read on average every day?
Xiao Ming read a book for the first 4 days and read 15 pages, then read 6 pages every day for 5 days. We can use the following formula to calculate the average number of pages seen per day: Average number of pages read per day = total number of pages/days Substituting the total number of pages and the number of days into the formula, we get: Average number of pages read per day = 15 pages/4 days = 3 pages/day Therefore, Xiao Ming read an average of three pages a day.
Xiao Ming read a book. He read 72 pages in the first 4 days and 29 pages a day for the next 6 days. How many pages did he read on average every day?
If Xiaoming reads 72 pages in the first 4 days, then Xiaoming's total page count in the first 4 days is 72 pages. Reading 29 pages every day for the next 6 days would mean that the total number of pages for the next 6 days would be 29 pages x 6 days = 171 pages. Therefore, Little Ming's total page count in the last six days was 171 pages. Little Ming read 171 pages per day for the next 6 days, 6 days = 27 pages. Therefore, Xiao Ming read an average of 27 pages a day.
