When 60% of a number is subtracted from another number, the second number reduces to its 52%; the ratio of the first number to the second number is :
-
- 6: 5
- 5: 3
- 5: 4
- 4: 5
Correct Option: D
Let the first number be p and second number be q.
| ∴ q - | = | |||
| 100 | 100 |
⇒ 100q – 60p = 52q
⇒ 48q = 60p
| ∴ | = | = | or 4 : 5 | |||
| y | 60 | 5 |
