Answer:_______________ |
| 1) If 23 is subtracted from a number, the result is 79. Find the number. Answer: 102 SOLUTION 1 : Let the required number be x. Given: x - 23 = 79 ⇒ x = 79 + 23 ( on transposing - 23, becomes + 23 ). ⇒ x = 102. Hence, the required number is 102. |
| 2) If 24 is subtracted from a number, the result is 71. Find the number. Answer: 95 SOLUTION 1 : Let the required number be y. Given: y - 24 = 71 ⇒ y = 71 + 24 ( on transposing - 24, becomes + 24 ). ⇒ y = 95. Hence, the required number is 95. |
| 3) If 38 is subtracted from a number, the result is 75. Find the number. Answer: 113 SOLUTION 1 : Let the required number be y. Given: y - 38 = 75 ⇒ y = 75 + 38 ( on transposing - 38, becomes + 38 ). ⇒ y = 113. Hence, the required number is 113. |
| 4) If 34 is subtracted from a number, the result is 71. Find the number. Answer: 105 SOLUTION 1 : Let the required number be x. Given: x - 34 = 71 ⇒ x = 71 + 34 ( on transposing - 34, becomes + 34 ). ⇒ x = 105. Hence, the required number is 105. |
| 5) If 27 is subtracted from a number, the result is 54. Find the number. Answer: 81 SOLUTION 1 : Let the required number be y. Given: y - 27 = 54 ⇒ y = 54 + 27 ( on transposing - 27, becomes + 27 ). ⇒ y = 81. Hence, the required number is 81. |
| 6) If 23 is subtracted from a number, the result is 67. Find the number. Answer: 90 SOLUTION 1 : Let the required number be x. Given: x - 23 = 67 ⇒ x = 67 + 23 ( on transposing - 23, becomes + 23 ). ⇒ x = 90. Hence, the required number is 90. |
| 7) If 30 is subtracted from a number, the result is 57. Find the number. Answer: 87 SOLUTION 1 : Let the required number be y. Given: y - 30 = 57 ⇒ y = 57 + 30 ( on transposing - 30, becomes + 30 ). ⇒ y = 87. Hence, the required number is 87. |
| 8) If 39 is subtracted from a number, the result is 76. Find the number. Answer: 115 SOLUTION 1 : Let the required number be x. Given: x - 39 = 76 ⇒ x = 76 + 39 ( on transposing - 39, becomes + 39 ). ⇒ x = 115. Hence, the required number is 115. |
| 9) If 37 is subtracted from a number, the result is 59. Find the number. Answer: 96 SOLUTION 1 : Let the required number be y. Given: y - 37 = 59 ⇒ y = 59 + 37 ( on transposing - 37, becomes + 37 ). ⇒ y = 96. Hence, the required number is 96. |
| 10) If 35 is subtracted from a number, the result is 53. Find the number. Answer: 88 SOLUTION 1 : Let the required number be x. Given: x - 35 = 53 ⇒ x = 53 + 35 ( on transposing - 35, becomes + 35 ). ⇒ x = 88. Hence, the required number is 88. |
