An 85m long rod is divided into two parts. If one part is 2/3 of the other part, then the longer part (in metres) is :
-
- 34
-
56 2 3 - 85
- 51
Correct Option: D
Let the longer part be p.
∴ According to question,
| Shortest part = | |
| 3 |
| ∴ p + | p = 85m | |
| 3 |
| ⇒ | = 85 | |
| 3 |
| ⇒ | = 85 | |
| 3 |
∴ p = 51 m
Hence , the longer part is 51 m .
