Answer 2

Solution :-

Let us assume that, number of Rs.2 coins are x .

so,

→ Number of Rs. 1 coins = 3 * number of Rs.2 coins = 3x

then,

→ Total amount = Rs.150

→ 1 * number of Rs. 1 coins + 2 * number of Rs.2 coins = 150

→ 1 * 3x + 2 * x = 150

→ 3x + 2x = 150

→ 5x = 150

→ x = 30 coins (Ans.)

therefore,

→ Number of Rs. 1 coins = 3x = 3 * 30 = 90 coins (Ans.)

Hence, Number of Rs. 1 coins are 90 and Number of Rs. 2 coins are 30 .
