Answer:_______________ |
| 1) A number increased by 22 gives 44. Find the number. Answer: 22 SOLUTION 1 : Let the required number be x. Given: x + 22 = 44 ⇒ x = 44 - 22 ( on transposing + 22, becomes - 22 ). ⇒ x = 22. Hence, the required number is 22. |
| 2) A number increased by 15 gives 40. Find the number. Answer: 25 SOLUTION 1 : Let the required number be y. Given: y + 15 = 40 ⇒ y = 40 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 25. Hence, the required number is 25. |
| 3) A number increased by 26 gives 45. Find the number. Answer: 19 SOLUTION 1 : Let the required number be y. Given: y + 26 = 45 ⇒ y = 45 - 26 ( on transposing + 26, becomes - 26 ). ⇒ y = 19. Hence, the required number is 19. |
| 4) A number increased by 14 gives 46. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 14 = 46 ⇒ x = 46 - 14 ( on transposing + 14, becomes - 14 ). ⇒ x = 32. Hence, the required number is 32. |
| 5) A number increased by 15 gives 43. Find the number. Answer: 28 SOLUTION 1 : Let the required number be y. Given: y + 15 = 43 ⇒ y = 43 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 28. Hence, the required number is 28. |
| 6) A number increased by 19 gives 60. Find the number. Answer: 41 SOLUTION 1 : Let the required number be x. Given: x + 19 = 60 ⇒ x = 60 - 19 ( on transposing + 19, becomes - 19 ). ⇒ x = 41. Hence, the required number is 41. |
| 7) A number increased by 27 gives 54. Find the number. Answer: 27 SOLUTION 1 : Let the required number be y. Given: y + 27 = 54 ⇒ y = 54 - 27 ( on transposing + 27, becomes - 27 ). ⇒ y = 27. Hence, the required number is 27. |
| 8) A number increased by 18 gives 46. Find the number. Answer: 28 SOLUTION 1 : Let the required number be x. Given: x + 18 = 46 ⇒ x = 46 - 18 ( on transposing + 18, becomes - 18 ). ⇒ x = 28. Hence, the required number is 28. |
| 9) A number increased by 15 gives 46. Find the number. Answer: 31 SOLUTION 1 : Let the required number be y. Given: y + 15 = 46 ⇒ y = 46 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 31. Hence, the required number is 31. |
| 10) A number increased by 29 gives 56. Find the number. Answer: 27 SOLUTION 1 : Let the required number be x. Given: x + 29 = 56 ⇒ x = 56 - 29 ( on transposing + 29, becomes - 29 ). ⇒ x = 27. Hence, the required number is 27. |
