Let the number of coins be x.
2 rupee coin be 2x.
5 rupee coin be 5x.
1 rupee coin with the total number of coins is 40 will be 40 - 2x.
Given value is 120.
On solving (1), (2),(3),(4), we get
2x + 5x + (40-2x) = 120
2x + 5x + 40 - 2x = 120
5x + 40 = 120
x = 80/5
= 16.
The number of 2 coins and the 5 rupees coins will be x = 16.
Hope this helps!
