Answer 2

The answer is given below :

The ratio is 5 : 6

Let, the common ratio be x.

Then, 1 rupee coins are 5x and 2 rupee coins are 6x in numbers.

So,

5x one rupee coins = Rs 5x

and

6x two rupee coins = Rs 12x

Then,

5x + 12x = 85

=> 17x = 85

=> x = 5

Therefore, the number of one rupee and two rupee coins are 25 and 30 respectively.
