Answer:_______________ |
| 1) A number increased by 15 gives 56. Find the number. Answer: 41 SOLUTION 1 : Let the required number be x. Given: x + 15 = 56 ⇒ x = 56 - 15 ( on transposing + 15, becomes - 15 ). ⇒ x = 41. Hence, the required number is 41. |
| 2) A number increased by 11 gives 59. Find the number. Answer: 48 SOLUTION 1 : Let the required number be y. Given: y + 11 = 59 ⇒ y = 59 - 11 ( on transposing + 11, becomes - 11 ). ⇒ y = 48. Hence, the required number is 48. |
| 3) A number increased by 28 gives 55. Find the number. Answer: 27 SOLUTION 1 : Let the required number be y. Given: y + 28 = 55 ⇒ y = 55 - 28 ( on transposing + 28, becomes - 28 ). ⇒ y = 27. Hence, the required number is 27. |
| 4) A number increased by 18 gives 59. Find the number. Answer: 41 SOLUTION 1 : Let the required number be x. Given: x + 18 = 59 ⇒ x = 59 - 18 ( on transposing + 18, becomes - 18 ). ⇒ x = 41. Hence, the required number is 41. |
| 5) A number increased by 20 gives 40. Find the number. Answer: 20 SOLUTION 1 : Let the required number be y. Given: y + 20 = 40 ⇒ y = 40 - 20 ( on transposing + 20, becomes - 20 ). ⇒ y = 20. Hence, the required number is 20. |
| 6) A number increased by 25 gives 52. Find the number. Answer: 27 SOLUTION 1 : Let the required number be x. Given: x + 25 = 52 ⇒ x = 52 - 25 ( on transposing + 25, becomes - 25 ). ⇒ x = 27. Hence, the required number is 27. |
| 7) A number increased by 25 gives 57. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 25 = 57 ⇒ x = 57 - 25 ( on transposing + 25, becomes - 25 ). ⇒ x = 32. Hence, the required number is 32. |
| 8) A number increased by 28 gives 53. Find the number. Answer: 25 SOLUTION 1 : Let the required number be y. Given: y + 28 = 53 ⇒ y = 53 - 28 ( on transposing + 28, becomes - 28 ). ⇒ y = 25. Hence, the required number is 25. |
| 9) A number increased by 13 gives 47. Find the number. Answer: 34 SOLUTION 1 : Let the required number be x. Given: x + 13 = 47 ⇒ x = 47 - 13 ( on transposing + 13, becomes - 13 ). ⇒ x = 34. Hence, the required number is 34. |
| 10) A number increased by 29 gives 44. Find the number. Answer: 15 SOLUTION 1 : Let the required number be y. Given: y + 29 = 44 ⇒ y = 44 - 29 ( on transposing + 29, becomes - 29 ). ⇒ y = 15. Hence, the required number is 15. |
