10) A number increased by 13 gives 58. Find the number.
Answer:_______________ |
1) A number increased by 13 gives 59. Find the number. Answer: 46 SOLUTION 1 : Let the required number be y. Given: y + 13 = 59 ⇒ y = 59 - 13 ( on transposing + 13, becomes - 13 ). ⇒ y = 46. Hence, the required number is 46. |
2) A number increased by 17 gives 54. Find the number. Answer: 37 SOLUTION 1 : Let the required number be x. Given: x + 17 = 54 ⇒ x = 54 - 17 ( on transposing + 17, becomes - 17 ). ⇒ x = 37. Hence, the required number is 37. |
3) A number increased by 15 gives 57. Find the number. Answer: 42 SOLUTION 1 : Let the required number be y. Given: y + 15 = 57 ⇒ y = 57 - 15 ( on transposing + 15, becomes - 15 ). ⇒ y = 42. Hence, the required number is 42. |
4) A number increased by 20 gives 53. Find the number. Answer: 33 SOLUTION 1 : Let the required number be x. Given: x + 20 = 53 ⇒ x = 53 - 20 ( on transposing + 20, becomes - 20 ). ⇒ x = 33. Hence, the required number is 33. |
5) A number increased by 27 gives 52. Find the number. Answer: 25 SOLUTION 1 : Let the required number be x. Given: x + 27 = 52 ⇒ x = 52 - 27 ( on transposing + 27, becomes - 27 ). ⇒ x = 25. Hence, the required number is 25. |
6) A number increased by 23 gives 44. Find the number. Answer: 21 SOLUTION 1 : Let the required number be y. Given: y + 23 = 44 ⇒ y = 44 - 23 ( on transposing + 23, becomes - 23 ). ⇒ y = 21. Hence, the required number is 21. |
7) A number increased by 15 gives 49. Find the number. Answer: 34 SOLUTION 1 : Let the required number be x. Given: x + 15 = 49 ⇒ x = 49 - 15 ( on transposing + 15, becomes - 15 ). ⇒ x = 34. Hence, the required number is 34. |
8) A number increased by 28 gives 40. Find the number. Answer: 12 SOLUTION 1 : Let the required number be y. Given: y + 28 = 40 ⇒ y = 40 - 28 ( on transposing + 28, becomes - 28 ). ⇒ y = 12. Hence, the required number is 12. |
9) A number increased by 14 gives 42. Find the number. Answer: 28 SOLUTION 1 : Let the required number be y. Given: y + 14 = 42 ⇒ y = 42 - 14 ( on transposing + 14, becomes - 14 ). ⇒ y = 28. Hence, the required number is 28. |
10) A number increased by 13 gives 58. Find the number. Answer: 45 SOLUTION 1 : Let the required number be x. Given: x + 13 = 58 ⇒ x = 58 - 13 ( on transposing + 13, becomes - 13 ). ⇒ x = 45. Hence, the required number is 45. |
