Answer:_______________ |
| 1) 6 years ago, I was 21 years old. How old am I now My present age is Answer: 27 SOLUTION 1 : Let my present age be x 6 years ago, my age was x - 6 Given, x - 6 = 21 x = 21 + 6 ( on transposing - 6, becomes + 6 ) ⇒ x = 27. Hence, my present age is 27. |
| 2) 8 years ago, I was 29 years old. How old am I now My present age is Answer: 37 SOLUTION 1 : Let my present age be x 8 years ago, my age was x - 8 Given, x - 8 = 29 x = 29 + 8 ( on transposing - 8, becomes + 8 ) ⇒ x = 37. Hence, my present age is 37. |
| 3) 11 years ago, I was 27 years old. How old am I now My present age is Answer: 38 SOLUTION 1 : Let my present age be y 11 years ago, my age was y - 11 Given, y - 11 = 27 y = 27 + 11 ( on transposing - 11, becomes + 11 ) ⇒ y = 38. Hence, my present age is 38. |
| 4) 10 years ago, I was 26 years old. How old am I now My present age is Answer: 36 SOLUTION 1 : Let my present age be x 10 years ago, my age was x - 10 Given, x - 10 = 26 x = 26 + 10 ( on transposing - 10, becomes + 10 ) ⇒ x = 36. Hence, my present age is 36. |
| 5) 10 years ago, I was 25 years old. How old am I now My present age is Answer: 35 SOLUTION 1 : Let my present age be y 10 years ago, my age was y - 10 Given, y - 10 = 25 y = 25 + 10 ( on transposing - 10, becomes + 10 ) ⇒ y = 35. Hence, my present age is 35. |
| 6) 9 years ago, I was 22 years old. How old am I now My present age is Answer: 31 SOLUTION 1 : Let my present age be y 9 years ago, my age was y - 9 Given, y - 9 = 22 y = 22 + 9 ( on transposing - 9, becomes + 9 ) ⇒ y = 31. Hence, my present age is 31. |
| 7) 10 years ago, I was 21 years old. How old am I now My present age is Answer: 31 SOLUTION 1 : Let my present age be x 10 years ago, my age was x - 10 Given, x - 10 = 21 x = 21 + 10 ( on transposing - 10, becomes + 10 ) ⇒ x = 31. Hence, my present age is 31. |
| 8) 7 years ago, I was 30 years old. How old am I now My present age is Answer: 37 SOLUTION 1 : Let my present age be x 7 years ago, my age was x - 7 Given, x - 7 = 30 x = 30 + 7 ( on transposing - 7, becomes + 7 ) ⇒ x = 37. Hence, my present age is 37. |
| 9) 11 years ago, I was 22 years old. How old am I now My present age is Answer: 33 SOLUTION 1 : Let my present age be y 11 years ago, my age was y - 11 Given, y - 11 = 22 y = 22 + 11 ( on transposing - 11, becomes + 11 ) ⇒ y = 33. Hence, my present age is 33. |
| 10) 8 years ago, I was 22 years old. How old am I now My present age is Answer: 30 SOLUTION 1 : Let my present age be y 8 years ago, my age was y - 8 Given, y - 8 = 22 y = 22 + 8 ( on transposing - 8, becomes + 8 ) ⇒ y = 30. Hence, my present age is 30. |
