Alex spent three sevenths of his moneyHe gave one fourth of the remainder to his sisterHe had 120 leftHow much money did he have in the beginning?

Answer 1

Spent and gave away: 3/7+1/4 which is equal to 19/28 with 9/28 left over 9/28 = 120 Divide 120 by 9 and multiply the quotient by 28 to find the original amount 1/28 = 13 and 1/3 13 and 1/3 x 28 = 373 and 1/3 which was the original amount 373 and 1/3 x 19/28 = 253 and 1/3 which is the amount spent and given away 373 and 1/3 - 253 and 1/3 = 120 So the original amount in the beginning was 373 and 1/3 units of money
