Question

A beverage stall has 70 bottles of orange juice and 48 bottles of mango juice. Every day the stall uses 5 bottles of orange juice and 3 bottles of mango juice. After how many days, the remainder bottles of both juices are the same? And find the number of remainder bottles.

Answer 1

70 - 5 d = 48 - 3 d

2 d = 22
d = 11

70 - 5 d = 70 - 55 = 15
48 - 3 d = 48 - 33 = 15 luckily
