# Heena has only Rs2 and Rs5 coins in her purse.

Heena has only Rs2 and Rs5 coins in her purse. If in all she has 80 coins in her purse amounting to Rs232, Find the number of Rs5 coins.

Syeda

Answer. Given total number of coins = 80 Let the number of Rs 2 coins be x Therefore number of Rs 5 coins = (80 – x) Total amount in the purse = Rs 232 That is 2x + 5(80 – x) = 232 2x + 400 – 5x = 232 400 – 232 = 3x 168 = 3x x = 56 80 –x = 80 – 56 = 24 Thus there are 56 coins of Rs 2 and 24 coins of Rs 5 SME Approved
