| 10) If 25 is subtracted from a number, the result is 52. Find the number.
Answer:_______________ |
| 1) If 32 is subtracted from a number, the result is 57. Find the number. Answer: 89 SOLUTION 1 : Let the required number be x. Given: x - 32 = 57 ⇒ x = 57 + 32 ( on transposing - 32, becomes + 32 ). ⇒ x = 89. Hence, the required number is 89. |
| 2) If 37 is subtracted from a number, the result is 57. Find the number. Answer: 94 SOLUTION 1 : Let the required number be y. Given: y - 37 = 57 ⇒ y = 57 + 37 ( on transposing - 37, becomes + 37 ). ⇒ y = 94. Hence, the required number is 94. |
| 3) If 22 is subtracted from a number, the result is 56. Find the number. Answer: 78 SOLUTION 1 : Let the required number be x. Given: x - 22 = 56 ⇒ x = 56 + 22 ( on transposing - 22, becomes + 22 ). ⇒ x = 78. Hence, the required number is 78. |
| 4) If 24 is subtracted from a number, the result is 51. Find the number. Answer: 75 SOLUTION 1 : Let the required number be y. Given: y - 24 = 51 ⇒ y = 51 + 24 ( on transposing - 24, becomes + 24 ). ⇒ y = 75. Hence, the required number is 75. |
| 5) If 22 is subtracted from a number, the result is 69. Find the number. Answer: 91 SOLUTION 1 : Let the required number be y. Given: y - 22 = 69 ⇒ y = 69 + 22 ( on transposing - 22, becomes + 22 ). ⇒ y = 91. Hence, the required number is 91. |
| 6) If 29 is subtracted from a number, the result is 78. Find the number. Answer: 107 SOLUTION 1 : Let the required number be x. Given: x - 29 = 78 ⇒ x = 78 + 29 ( on transposing - 29, becomes + 29 ). ⇒ x = 107. Hence, the required number is 107. |
| 7) If 29 is subtracted from a number, the result is 58. Find the number. Answer: 87 SOLUTION 1 : Let the required number be x. Given: x - 29 = 58 ⇒ x = 58 + 29 ( on transposing - 29, becomes + 29 ). ⇒ x = 87. Hence, the required number is 87. |
| 8) If 37 is subtracted from a number, the result is 80. Find the number. Answer: 117 SOLUTION 1 : Let the required number be y. Given: y - 37 = 80 ⇒ y = 80 + 37 ( on transposing - 37, becomes + 37 ). ⇒ y = 117. Hence, the required number is 117. |
| 9) If 29 is subtracted from a number, the result is 72. Find the number. Answer: 101 SOLUTION 1 : Let the required number be x. Given: x - 29 = 72 ⇒ x = 72 + 29 ( on transposing - 29, becomes + 29 ). ⇒ x = 101. Hence, the required number is 101. |
| 10) If 25 is subtracted from a number, the result is 52. Find the number. Answer: 77 SOLUTION 1 : Let the required number be y. Given: y - 25 = 52 ⇒ y = 52 + 25 ( on transposing - 25, becomes + 25 ). ⇒ y = 77. Hence, the required number is 77. |
