Answer 1

Answer:

90

Explanation: Let there are n two-rupee coins. So, there must be 3n one-rupee coins.

Amount of 3n one rupee = 3n(1) = 3n

Amount of n two rupees = (n)(2) = 2n Total amount = Rs 150

2n + 3n = 150

or, 5n = 150

or, n = 150/5

= 30

There are 3n one-rupee coins, hence,

there 3n = 3(30) = 90 coins
