Answer 2

Step-by-step explanation:

Let the number of 2 rupee coins be x

then the no. of 1 rupee coin will be 4x.

value of 2 rupee coins = 2×x =2x

value of 1 rupee coins = 1 ×4x = 4x

Total money = ₹90

=> 2x + 4x =90

=> 6x = 90

=> x = 90/6 = 15

x = 15, means

number of 2 rupee coins = 15

number of 1 rupee coins = 4 × 15 = 60
