| 10) The sum of two numbers is 51. If one number is 16, what is the other number
Answer:_______________ |
| 1) The sum of two numbers is 42. If one number is 20, what is the other number Answer: 22 SOLUTION 1 : Let the required number y. Given: 20 + y = 42. ⇒ y = 42 - 20 ( on transposing + 20 becomes - 20 ). ⇒ y = 22. Hence, the requried number is 22. |
| 2) The sum of two numbers is 55. If one number is 21, what is the other number Answer: 34 SOLUTION 1 : Let the required number x. Given: 21 + x = 55. ⇒ x = 55 - 21 ( on transposing + 21 becomes - 21 ). ⇒ x = 34. Hence, the requried number is 34. |
| 3) The sum of two numbers is 46. If one number is 18, what is the other number Answer: 28 SOLUTION 1 : Let the required number y. Given: 18 + y = 46. ⇒ y = 46 - 18 ( on transposing + 18 becomes - 18 ). ⇒ y = 28. Hence, the requried number is 28. |
| 4) The sum of two numbers is 40. If one number is 14, what is the other number Answer: 26 SOLUTION 1 : Let the required number x. Given: 14 + x = 40. ⇒ x = 40 - 14 ( on transposing + 14 becomes - 14 ). ⇒ x = 26. Hence, the requried number is 26. |
| 5) The sum of two numbers is 49. If one number is 26, what is the other number Answer: 23 SOLUTION 1 : Let the required number x. Given: 26 + x = 49. ⇒ x = 49 - 26 ( on transposing + 26 becomes - 26 ). ⇒ x = 23. Hence, the requried number is 23. |
| 6) The sum of two numbers is 58. If one number is 20, what is the other number Answer: 38 SOLUTION 1 : Let the required number y. Given: 20 + y = 58. ⇒ y = 58 - 20 ( on transposing + 20 becomes - 20 ). ⇒ y = 38. Hence, the requried number is 38. |
| 7) The sum of two numbers is 51. If one number is 19, what is the other number Answer: 32 SOLUTION 1 : Let the required number y. Given: 19 + y = 51. ⇒ y = 51 - 19 ( on transposing + 19 becomes - 19 ). ⇒ y = 32. Hence, the requried number is 32. |
| 8) The sum of two numbers is 44. If one number is 26, what is the other number Answer: 18 SOLUTION 1 : Let the required number x. Given: 26 + x = 44. ⇒ x = 44 - 26 ( on transposing + 26 becomes - 26 ). ⇒ x = 18. Hence, the requried number is 18. |
| 9) The sum of two numbers is 45. If one number is 15, what is the other number Answer: 30 SOLUTION 1 : Let the required number y. Given: 15 + y = 45. ⇒ y = 45 - 15 ( on transposing + 15 becomes - 15 ). ⇒ y = 30. Hence, the requried number is 30. |
| 10) The sum of two numbers is 51. If one number is 16, what is the other number Answer: 35 SOLUTION 1 : Let the required number x. Given: 16 + x = 51. ⇒ x = 51 - 16 ( on transposing + 16 becomes - 16 ). ⇒ x = 35. Hence, the requried number is 35. |
