Answer:_______________ |
| 1) A number increased by 30 gives 49. Find the number. Answer: 19 SOLUTION 1 : Let the required number be y. Given: y + 30 = 49 ⇒ y = 49 - 30 ( on transposing + 30, becomes - 30 ). ⇒ y = 19. Hence, the required number is 19. |
| 2) A number increased by 29 gives 53. Find the number. Answer: 24 SOLUTION 1 : Let the required number be x. Given: x + 29 = 53 ⇒ x = 53 - 29 ( on transposing + 29, becomes - 29 ). ⇒ x = 24. Hence, the required number is 24. |
| 3) A number increased by 27 gives 46. Find the number. Answer: 19 SOLUTION 1 : Let the required number be y. Given: y + 27 = 46 ⇒ y = 46 - 27 ( on transposing + 27, becomes - 27 ). ⇒ y = 19. Hence, the required number is 19. |
| 4) A number increased by 20 gives 55. Find the number. Answer: 35 SOLUTION 1 : Let the required number be y. Given: y + 20 = 55 ⇒ y = 55 - 20 ( on transposing + 20, becomes - 20 ). ⇒ y = 35. Hence, the required number is 35. |
| 5) A number increased by 22 gives 54. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 22 = 54 ⇒ x = 54 - 22 ( on transposing + 22, becomes - 22 ). ⇒ x = 32. Hence, the required number is 32. |
| 6) A number increased by 17 gives 40. Find the number. Answer: 23 SOLUTION 1 : Let the required number be y. Given: y + 17 = 40 ⇒ y = 40 - 17 ( on transposing + 17, becomes - 17 ). ⇒ y = 23. Hence, the required number is 23. |
| 7) A number increased by 20 gives 52. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 20 = 52 ⇒ x = 52 - 20 ( on transposing + 20, becomes - 20 ). ⇒ x = 32. Hence, the required number is 32. |
| 8) A number increased by 14 gives 40. Find the number. Answer: 26 SOLUTION 1 : Let the required number be y. Given: y + 14 = 40 ⇒ y = 40 - 14 ( on transposing + 14, becomes - 14 ). ⇒ y = 26. Hence, the required number is 26. |
| 9) A number increased by 17 gives 41. Find the number. Answer: 24 SOLUTION 1 : Let the required number be x. Given: x + 17 = 41 ⇒ x = 41 - 17 ( on transposing + 17, becomes - 17 ). ⇒ x = 24. Hence, the required number is 24. |
| 10) A number increased by 12 gives 44. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 12 = 44 ⇒ x = 44 - 12 ( on transposing + 12, becomes - 12 ). ⇒ x = 32. Hence, the required number is 32. |
