Question

A company made 4 million in the second quarter this is one third more than I made in the first quarter and forfeits of what I made in the third quarter how much did the company make in the three quarters combined

Answer 1

From the given: 2nd quarter = 4 million
 Let x  and y be the amount made in the first and third quarter such that,
                     1st quarter:    4 = (x + x/3)    ; x = 3 million
                      3rd quarter:   4 = (4/5)y       ;  y = 5 million

Adding together the amounts for the first three quarter is become 12 million.
