The remainder and the total amount on the washing machine and the savings are the same. Make the remainder and the total amount on the washing machine and the savings the same. LCM of 3 and 5 is 15.
Total salary = 20 u
Amount spent of the television set = 5 u
Amount spent on the washing machine = 6 u
Amount of savings = 9 u
9 u = 225
1 u = 225 ÷ 9 = 25
Min's salary
= 20 u
= 20 x 25
= $500
Answer(s): $500
