Answer:
Number of 1 rupee coin = 24
Number of 2 rupees coin = 12
Step-by-step explanation:
let the number of two rupees coins be x. since number of 1 rupee coin is double of number of two rupees coin.
so,
number of 1 rupee coin = 2x
given the total value of coin = 36
so,
According to the question,
2x + x = 36
3x = 36
x = 36/3
x = 12
so,
number of 2 rupees coins = 12
number of 1 rupee coin = 2x
= 2 × 12
= 24
so,
Number of 1 rupee coin = 24
Number of 2 rupees coin = 12
