80% of the total proit is divided in the ratio
20000: 24000: 16000 = 5 : 6 : 4
80% of total profit = 5x + 6x + 4x = 15x
Total profit =(15x/80%)= 18.75x
Share of C in profit = 4x + 20% of 18.75
= 4x + 3.75x = 7.75x
∴Share of A in proit = 5x
Share of B in proit = 6x
∴(6z + 5x) - 7.75x = 487.50
⇒3.25x = 487.50
⇒x = 150
∴Total profit = 18.75 x 150 = Z 2812.50.
