| 10) The sum of two numbers is 43. If one number is 18, what is the other number
Answer:_______________ |
| 1) The sum of two numbers is 47. If one number is 28, what is the other number Answer: 19 SOLUTION 1 : Let the required number x. Given: 28 + x = 47. ⇒ x = 47 - 28 ( on transposing + 28 becomes - 28 ). ⇒ x = 19. Hence, the requried number is 19. |
| 2) The sum of two numbers is 55. If one number is 28, what is the other number Answer: 27 SOLUTION 1 : Let the required number y. Given: 28 + y = 55. ⇒ y = 55 - 28 ( on transposing + 28 becomes - 28 ). ⇒ y = 27. Hence, the requried number is 27. |
| 3) The sum of two numbers is 43. If one number is 29, what is the other number Answer: 14 SOLUTION 1 : Let the required number x. Given: 29 + x = 43. ⇒ x = 43 - 29 ( on transposing + 29 becomes - 29 ). ⇒ x = 14. Hence, the requried number is 14. |
| 4) The sum of two numbers is 48. If one number is 12, what is the other number Answer: 36 SOLUTION 1 : Let the required number y. Given: 12 + y = 48. ⇒ y = 48 - 12 ( on transposing + 12 becomes - 12 ). ⇒ y = 36. Hence, the requried number is 36. |
| 5) The sum of two numbers is 40. If one number is 24, what is the other number Answer: 16 SOLUTION 1 : Let the required number y. Given: 24 + y = 40. ⇒ y = 40 - 24 ( on transposing + 24 becomes - 24 ). ⇒ y = 16. Hence, the requried number is 16. |
| 6) The sum of two numbers is 50. If one number is 12, what is the other number Answer: 38 SOLUTION 1 : Let the required number x. Given: 12 + x = 50. ⇒ x = 50 - 12 ( on transposing + 12 becomes - 12 ). ⇒ x = 38. Hence, the requried number is 38. |
| 7) The sum of two numbers is 57. If one number is 15, what is the other number Answer: 42 SOLUTION 1 : Let the required number y. Given: 15 + y = 57. ⇒ y = 57 - 15 ( on transposing + 15 becomes - 15 ). ⇒ y = 42. Hence, the requried number is 42. |
| 8) The sum of two numbers is 59. If one number is 30, what is the other number Answer: 29 SOLUTION 1 : Let the required number x. Given: 30 + x = 59. ⇒ x = 59 - 30 ( on transposing + 30 becomes - 30 ). ⇒ x = 29. Hence, the requried number is 29. |
| 9) The sum of two numbers is 45. If one number is 28, what is the other number Answer: 17 SOLUTION 1 : Let the required number y. Given: 28 + y = 45. ⇒ y = 45 - 28 ( on transposing + 28 becomes - 28 ). ⇒ y = 17. Hence, the requried number is 17. |
| 10) The sum of two numbers is 43. If one number is 18, what is the other number Answer: 25 SOLUTION 1 : Let the required number x. Given: 18 + x = 43. ⇒ x = 43 - 18 ( on transposing + 18 becomes - 18 ). ⇒ x = 25. Hence, the requried number is 25. |
