Answer:_______________ |
| 1) A number increased by 27 gives 50. Find the number. Answer: 23 SOLUTION 1 : Let the required number be x. Given: x + 27 = 50 ⇒ x = 50 - 27 ( on transposing + 27, becomes - 27 ). ⇒ x = 23. Hence, the required number is 23. |
| 2) A number increased by 24 gives 49. Find the number. Answer: 25 SOLUTION 1 : Let the required number be y. Given: y + 24 = 49 ⇒ y = 49 - 24 ( on transposing + 24, becomes - 24 ). ⇒ y = 25. Hence, the required number is 25. |
| 3) A number increased by 15 gives 40. Find the number. Answer: 25 SOLUTION 1 : Let the required number be x. Given: x + 15 = 40 ⇒ x = 40 - 15 ( on transposing + 15, becomes - 15 ). ⇒ x = 25. Hence, the required number is 25. |
| 4) A number increased by 26 gives 45. Find the number. Answer: 19 SOLUTION 1 : Let the required number be y. Given: y + 26 = 45 ⇒ y = 45 - 26 ( on transposing + 26, becomes - 26 ). ⇒ y = 19. Hence, the required number is 19. |
| 5) A number increased by 16 gives 58. Find the number. Answer: 42 SOLUTION 1 : Let the required number be x. Given: x + 16 = 58 ⇒ x = 58 - 16 ( on transposing + 16, becomes - 16 ). ⇒ x = 42. Hence, the required number is 42. |
| 6) A number increased by 25 gives 57. Find the number. Answer: 32 SOLUTION 1 : Let the required number be y. Given: y + 25 = 57 ⇒ y = 57 - 25 ( on transposing + 25, becomes - 25 ). ⇒ y = 32. Hence, the required number is 32. |
| 7) A number increased by 14 gives 42. Find the number. Answer: 28 SOLUTION 1 : Let the required number be x. Given: x + 14 = 42 ⇒ x = 42 - 14 ( on transposing + 14, becomes - 14 ). ⇒ x = 28. Hence, the required number is 28. |
| 8) A number increased by 15 gives 50. Find the number. Answer: 35 SOLUTION 1 : Let the required number be y. Given: y + 15 = 50 ⇒ y = 50 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 35. Hence, the required number is 35. |
| 9) A number increased by 26 gives 44. Find the number. Answer: 18 SOLUTION 1 : Let the required number be y. Given: y + 26 = 44 ⇒ y = 44 - 26 ( on transposing + 26, becomes - 26 ). ⇒ y = 18. Hence, the required number is 18. |
| 10) A number increased by 26 gives 43. Find the number. Answer: 17 SOLUTION 1 : Let the required number be x. Given: x + 26 = 43 ⇒ x = 43 - 26 ( on transposing + 26, becomes - 26 ). ⇒ x = 17. Hence, the required number is 17. |
