| 10) The sum of two numbers is 48. If one number is 22, what is the other number
Answer:_______________ |
| 1) The sum of two numbers is 52. If one number is 23, what is the other number Answer: 29 SOLUTION 1 : Let the required number x. Given: 23 + x = 52. ⇒ x = 52 - 23 ( on transposing + 23 becomes - 23 ). ⇒ x = 29. Hence, the requried number is 29. |
| 2) The sum of two numbers is 40. If one number is 27, what is the other number Answer: 13 SOLUTION 1 : Let the required number y. Given: 27 + y = 40. ⇒ y = 40 - 27 ( on transposing + 27 becomes - 27 ). ⇒ y = 13. Hence, the requried number is 13. |
| 3) The sum of two numbers is 46. If one number is 22, what is the other number Answer: 24 SOLUTION 1 : Let the required number y. Given: 22 + y = 46. ⇒ y = 46 - 22 ( on transposing + 22 becomes - 22 ). ⇒ y = 24. Hence, the requried number is 24. |
| 4) The sum of two numbers is 50. If one number is 21, what is the other number Answer: 29 SOLUTION 1 : Let the required number x. Given: 21 + x = 50. ⇒ x = 50 - 21 ( on transposing + 21 becomes - 21 ). ⇒ x = 29. Hence, the requried number is 29. |
| 5) 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. |
| 6) The sum of two numbers is 45. If one number is 14, what is the other number Answer: 31 SOLUTION 1 : Let the required number y. Given: 14 + y = 45. ⇒ y = 45 - 14 ( on transposing + 14 becomes - 14 ). ⇒ y = 31. Hence, the requried number is 31. |
| 7) The sum of two numbers is 45. If one number is 20, what is the other number Answer: 25 SOLUTION 1 : Let the required number x. Given: 20 + x = 45. ⇒ x = 45 - 20 ( on transposing + 20 becomes - 20 ). ⇒ x = 25. Hence, the requried number is 25. |
| 8) The sum of two numbers is 60. If one number is 25, what is the other number Answer: 35 SOLUTION 1 : Let the required number y. Given: 25 + y = 60. ⇒ y = 60 - 25 ( on transposing + 25 becomes - 25 ). ⇒ y = 35. Hence, the requried number is 35. |
| 9) The sum of two numbers is 45. If one number is 21, what is the other number Answer: 24 SOLUTION 1 : Let the required number y. Given: 21 + y = 45. ⇒ y = 45 - 21 ( on transposing + 21 becomes - 21 ). ⇒ y = 24. Hence, the requried number is 24. |
| 10) The sum of two numbers is 48. If one number is 22, what is the other number Answer: 26 SOLUTION 1 : Let the required number x. Given: 22 + x = 48. ⇒ x = 48 - 22 ( on transposing + 22 becomes - 22 ). ⇒ x = 26. Hence, the requried number is 26. |
