Answer:

30

Step-by-step explanation:

Let the number of one rupee coins be 5x and that of two rupee coins be 6x.

Now, value of 5x one rupee coins = Rs. 1×5x= Rs. 5x and

value of 6x two rupee coins = Rs. 2×6x= Rs. 12x

Given, value of coins = Rs. 85

⇒5x+12x=85

⇒17x=85

⇒x=5

So, the number of two rupee coins =6×5=30

Hence, there are total 30 two rupee coins in the money box.
