The remainder and the total amount on the gas stove and the savings are the same. Make the remainder and the total amount on the gas stove and the savings the same. LCM of 3 and 5 is 15.
Total salary = 25 u
Amount spent of the refrigerator = 10 u
Amount spent on the gas stove = 9 u
Amount of savings = 6 u
6 u = 126
1 u = 126 ÷ 6 = 21
Xuan's salary
= 25 u
= 25 x 21
= $525
Answer(s): $525
