Answer:_______________ |
| 1) If 35 is subtracted from a number, the result is 77. Find the number. Answer: 112 SOLUTION 1 : Let the required number be x. Given: x - 35 = 77 ⇒ x = 77 + 35 ( on transposing - 35, becomes + 35 ). ⇒ x = 112. Hence, the required number is 112. |
| 2) If 40 is subtracted from a number, the result is 62. Find the number. Answer: 102 SOLUTION 1 : Let the required number be y. Given: y - 40 = 62 ⇒ y = 62 + 40 ( on transposing - 40, becomes + 40 ). ⇒ y = 102. Hence, the required number is 102. |
| 3) If 36 is subtracted from a number, the result is 75. Find the number. Answer: 111 SOLUTION 1 : Let the required number be x. Given: x - 36 = 75 ⇒ x = 75 + 36 ( on transposing - 36, becomes + 36 ). ⇒ x = 111. Hence, the required number is 111. |
| 4) If 21 is subtracted from a number, the result is 69. Find the number. Answer: 90 SOLUTION 1 : Let the required number be y. Given: y - 21 = 69 ⇒ y = 69 + 21 ( on transposing - 21, becomes + 21 ). ⇒ y = 90. Hence, the required number is 90. |
| 5) If 27 is subtracted from a number, the result is 65. Find the number. Answer: 92 SOLUTION 1 : Let the required number be x. Given: x - 27 = 65 ⇒ x = 65 + 27 ( on transposing - 27, becomes + 27 ). ⇒ x = 92. Hence, the required number is 92. |
| 6) If 31 is subtracted from a number, the result is 77. Find the number. Answer: 108 SOLUTION 1 : Let the required number be y. Given: y - 31 = 77 ⇒ y = 77 + 31 ( on transposing - 31, becomes + 31 ). ⇒ y = 108. Hence, the required number is 108. |
| 7) If 31 is subtracted from a number, the result is 72. Find the number. Answer: 103 SOLUTION 1 : Let the required number be x. Given: x - 31 = 72 ⇒ x = 72 + 31 ( on transposing - 31, becomes + 31 ). ⇒ x = 103. Hence, the required number is 103. |
| 8) If 25 is subtracted from a number, the result is 57. Find the number. Answer: 82 SOLUTION 1 : Let the required number be y. Given: y - 25 = 57 ⇒ y = 57 + 25 ( on transposing - 25, becomes + 25 ). ⇒ y = 82. Hence, the required number is 82. |
| 9) If 38 is subtracted from a number, the result is 71. Find the number. Answer: 109 SOLUTION 1 : Let the required number be y. Given: y - 38 = 71 ⇒ y = 71 + 38 ( on transposing - 38, becomes + 38 ). ⇒ y = 109. Hence, the required number is 109. |
| 10) If 36 is subtracted from a number, the result is 72. Find the number. Answer: 108 SOLUTION 1 : Let the required number be x. Given: x - 36 = 72 ⇒ x = 72 + 36 ( on transposing - 36, becomes + 36 ). ⇒ x = 108. Hence, the required number is 108. |
