Answer:
35 and 20
Step-by-step explanation:
No. of 1 rupee coins be x
No. of 2 rupee coins be y
Value of 1 rupee coin = 1 × x = Rs. x
Value of 2 rupee coin = 2 × y = Rs. 2y
No. of total coins are 55. So,
x+y =55 (eqn.1)
Total value of money is Rs. 75. So,
x+2y = 75 (eqn.2)
Solve the two equations.
x+y =55
x+2y = 75
-------------
y = 20
So, no. of 2 rupee coins = 20
No. of 1 rupee coin
x+20 = 55
x = 35
For check,
Total value => x+2y =75
35+(2×20) = 75
35+40 = 75
75 = 75
So, total number of 1 rupee and 2 rupee coins are 35 and 20 respectively.
