Answer:_______________ |
| 1) A number increased by 12 gives 44. Find the number. Answer: 32 SOLUTION 1 : Let the required number be y. Given: y + 12 = 44 ⇒ y = 44 - 12 ( on transposing + 12, becomes - 12 ). ⇒ y = 32. Hence, the required number is 32. |
| 2) A number increased by 19 gives 59. Find the number. Answer: 40 SOLUTION 1 : Let the required number be x. Given: x + 19 = 59 ⇒ x = 59 - 19 ( on transposing + 19, becomes - 19 ). ⇒ x = 40. Hence, the required number is 40. |
| 3) A number increased by 16 gives 45. Find the number. Answer: 29 SOLUTION 1 : Let the required number be y. Given: y + 16 = 45 ⇒ y = 45 - 16 ( on transposing + 16, becomes - 16 ). ⇒ y = 29. Hence, the required number is 29. |
| 4) A number increased by 17 gives 47. Find the number. Answer: 30 SOLUTION 1 : Let the required number be x. Given: x + 17 = 47 ⇒ x = 47 - 17 ( on transposing + 17, becomes - 17 ). ⇒ x = 30. Hence, the required number is 30. |
| 5) A number increased by 15 gives 42. Find the number. Answer: 27 SOLUTION 1 : Let the required number be y. Given: y + 15 = 42 ⇒ y = 42 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 27. Hence, the required number is 27. |
| 6) A number increased by 14 gives 49. Find the number. Answer: 35 SOLUTION 1 : Let the required number be x. Given: x + 14 = 49 ⇒ x = 49 - 14 ( on transposing + 14, becomes - 14 ). ⇒ x = 35. Hence, the required number is 35. |
| 7) A number increased by 22 gives 45. Find the number. Answer: 23 SOLUTION 1 : Let the required number be y. Given: y + 22 = 45 ⇒ y = 45 - 22 ( on transposing + 22, becomes - 22 ). ⇒ y = 23. Hence, the required number is 23. |
| 8) A number increased by 28 gives 46. Find the number. Answer: 18 SOLUTION 1 : Let the required number be x. Given: x + 28 = 46 ⇒ x = 46 - 28 ( on transposing + 28, becomes - 28 ). ⇒ x = 18. Hence, the required number is 18. |
| 9) A number increased by 24 gives 51. Find the number. Answer: 27 SOLUTION 1 : Let the required number be y. Given: y + 24 = 51 ⇒ y = 51 - 24 ( on transposing + 24, becomes - 24 ). ⇒ y = 27. Hence, the required number is 27. |
| 10) A number increased by 12 gives 53. Find the number. Answer: 41 SOLUTION 1 : Let the required number be x. Given: x + 12 = 53 ⇒ x = 53 - 12 ( on transposing + 12, becomes - 12 ). ⇒ x = 41. Hence, the required number is 41. |
