Question

Bansi has 3 times as many two rupee coins as he has five rupee coins. If he has in all a sum of Rs.77 . how many coins of each denominations does he have ?

Answer 1

hey!!


the answer is 25

Answer 2

Answer:

Let Bansi has x coin.

So, coins of ₹2 = 2 * x = 2x

And coins of ₹5 = 5 * x = 5x

From given condition,

=> 3 * (2x) = 6x

Sum of coins = 6x + 5x = 11x

=> 11x = 77

=> x = 77 ÷ 11

=> x = 7

3x = 3 * 7 = 21

Coins of ₹2 = x = 7

Coins of ₹5 = 3x = 3 * 7 = 21

Verification:

=> 42 + 35

=> 77
