Answer:_______________ |
| 1) A number increased by 30 gives 57. Find the number. Answer: 27 SOLUTION 1 : Let the required number be y. Given: y + 30 = 57 ⇒ y = 57 - 30 ( on transposing + 30, becomes - 30 ). ⇒ y = 27. Hence, the required number is 27. |
| 2) A number increased by 27 gives 44. Find the number. Answer: 17 SOLUTION 1 : Let the required number be x. Given: x + 27 = 44 ⇒ x = 44 - 27 ( on transposing + 27, becomes - 27 ). ⇒ x = 17. Hence, the required number is 17. |
| 3) A number increased by 15 gives 44. Find the number. Answer: 29 SOLUTION 1 : Let the required number be y. Given: y + 15 = 44 ⇒ y = 44 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 29. Hence, the required number is 29. |
| 4) A number increased by 20 gives 40. Find the number. Answer: 20 SOLUTION 1 : Let the required number be x. Given: x + 20 = 40 ⇒ x = 40 - 20 ( on transposing + 20, becomes - 20 ). ⇒ x = 20. Hence, the required number is 20. |
| 5) A number increased by 19 gives 42. Find the number. Answer: 23 SOLUTION 1 : Let the required number be y. Given: y + 19 = 42 ⇒ y = 42 - 19 ( on transposing + 19, becomes - 19 ). ⇒ y = 23. Hence, the required number is 23. |
| 6) A number increased by 24 gives 56. Find the number. Answer: 32 SOLUTION 1 : Let the required number be x. Given: x + 24 = 56 ⇒ x = 56 - 24 ( on transposing + 24, becomes - 24 ). ⇒ x = 32. Hence, the required number is 32. |
| 7) A number increased by 19 gives 57. Find the number. Answer: 38 SOLUTION 1 : Let the required number be y. Given: y + 19 = 57 ⇒ y = 57 - 19 ( on transposing + 19, becomes - 19 ). ⇒ y = 38. Hence, the required number is 38. |
| 8) A number increased by 15 gives 45. Find the number. Answer: 30 SOLUTION 1 : Let the required number be x. Given: x + 15 = 45 ⇒ x = 45 - 15 ( on transposing + 15, becomes - 15 ). ⇒ x = 30. Hence, the required number is 30. |
| 9) A number increased by 19 gives 52. Find the number. Answer: 33 SOLUTION 1 : Let the required number be x. Given: x + 19 = 52 ⇒ x = 52 - 19 ( on transposing + 19, becomes - 19 ). ⇒ x = 33. Hence, the required number is 33. |
| 10) A number increased by 25 gives 60. Find the number. Answer: 35 SOLUTION 1 : Let the required number be y. Given: y + 25 = 60 ⇒ y = 60 - 25 ( on transposing + 25, becomes - 25 ). ⇒ y = 35. Hence, the required number is 35. |
