Question

Bansi has some coins with ₹ 2 and some with ₹ 5. If the number of coins with ₹ 2 is three times the number of coins with ₹ 5 and the sum of their values ​​is Rs. 77, find the number of both types of coins.

Answer 1

Answer:

7 Rs 5 coins and 21 Rs 2 coins

Explanation:

Let number of Rs 2 coins be x

Let number of Rs 5 coins be y

Therefore, value of Rs 2 coins is 2x and value of Rs 5 coins is 5y

x = 3y

2x + 5y = 77

6y + 5y = 77

11y = 77

y = 7

x = 3y = 21
