Define x:
Let the number of 5-rupee coins be x
The number of 2-rupee coins will be 3x
Form equation and solve for x:
The total sum is Rs 77
5x + 2(3x) = 77
5x + 6x = 77
11x = 77
x = 7
Find the number of coins for each denomination:
5-rupees = x = 7
2-rupees = 3x = 3(7) = 21
Answer: Banti has 7 5-rupee coins and 21 2-rupee coins.
