Question

A supermarket had an equal number of bottles of shampoo and conditioner. After selling 82 bottles of shampoo and 178 bottles of conditioner, the no. of bottles of conditioner was 1/5 of the bottles of shampoo left. How many bottles of shampoo were left?

Answer 1

s = shampoo
c = conditioner

s = c to start
1/5(s-82) = c-178
s = c = 202

s-82 = 120
202-178 = 24 = 1/5 * (120)
