Question

In 2020, a company earned a profit of 10 per box of product A sold and a loss of 6 per box of product B sold.
What was the number of product A boxes it must have sold to have neither profit nor loss, if the number of product
B boxes sold was 3,500?
a) 3500
b) 2100
c) 2800
d) 3000​

Answer 1

let the no. of boxes of product A be x

Therefore,

according to question

10x - 6(3500) = 0

10x - 21000 = 0

10x = 21000

x = 21000÷10

x = 2100

option b)
