Ronnel spent 1/5 of his money to buy a food. He spent 1/4 of the remaining money to buy a magazine.If he had 360 pesos left in his wallet, how much money did he have at first?

Answer 1

amount of original money ---- x

(1/5)x + (1/4)(4/5)x + 360 = x
x/5 + x/5 + 360 = x
times 5, the LCD
x + x + 1800 = 5x
3x = 1800
x = 600

check:
he spent 1/5 of 600, or 120 , leaving him with 480
he spend 1/4 of 480 on food, leaving him with 360
