| 10) The sum of two numbers is 48. If one number is 21, what is the other number
Answer:_______________ |
| 1) The sum of two numbers is 45. If one number is 13, what is the other number Answer: 32 SOLUTION 1 : Let the required number x. Given: 13 + x = 45. ⇒ x = 45 - 13 ( on transposing + 13 becomes - 13 ). ⇒ x = 32. Hence, the requried number is 32. |
| 2) The sum of two numbers is 58. If one number is 26, what is the other number Answer: 32 SOLUTION 1 : Let the required number y. Given: 26 + y = 58. ⇒ y = 58 - 26 ( on transposing + 26 becomes - 26 ). ⇒ y = 32. Hence, the requried number is 32. |
| 3) The sum of two numbers is 41. If one number is 28, what is the other number Answer: 13 SOLUTION 1 : Let the required number y. Given: 28 + y = 41. ⇒ y = 41 - 28 ( on transposing + 28 becomes - 28 ). ⇒ y = 13. Hence, the requried number is 13. |
| 4) The sum of two numbers is 49. If one number is 27, what is the other number Answer: 22 SOLUTION 1 : Let the required number x. Given: 27 + x = 49. ⇒ x = 49 - 27 ( on transposing + 27 becomes - 27 ). ⇒ x = 22. Hence, the requried number is 22. |
| 5) The sum of two numbers is 52. If one number is 14, what is the other number Answer: 38 SOLUTION 1 : Let the required number y. Given: 14 + y = 52. ⇒ y = 52 - 14 ( on transposing + 14 becomes - 14 ). ⇒ y = 38. Hence, the requried number is 38. |
| 6) The sum of two numbers is 43. If one number is 26, what is the other number Answer: 17 SOLUTION 1 : Let the required number x. Given: 26 + x = 43. ⇒ x = 43 - 26 ( on transposing + 26 becomes - 26 ). ⇒ x = 17. Hence, the requried number is 17. |
| 7) The sum of two numbers is 53. If one number is 22, what is the other number Answer: 31 SOLUTION 1 : Let the required number x. Given: 22 + x = 53. ⇒ x = 53 - 22 ( on transposing + 22 becomes - 22 ). ⇒ x = 31. Hence, the requried number is 31. |
| 8) The sum of two numbers is 47. If one number is 17, what is the other number Answer: 30 SOLUTION 1 : Let the required number y. Given: 17 + y = 47. ⇒ y = 47 - 17 ( on transposing + 17 becomes - 17 ). ⇒ y = 30. Hence, the requried number is 30. |
| 9) The sum of two numbers is 60. If one number is 26, what is the other number Answer: 34 SOLUTION 1 : Let the required number x. Given: 26 + x = 60. ⇒ x = 60 - 26 ( on transposing + 26 becomes - 26 ). ⇒ x = 34. Hence, the requried number is 34. |
| 10) The sum of two numbers is 48. If one number is 21, what is the other number Answer: 27 SOLUTION 1 : Let the required number y. Given: 21 + y = 48. ⇒ y = 48 - 21 ( on transposing + 21 becomes - 21 ). ⇒ y = 27. Hence, the requried number is 27. |
