A and B share profits in the ratio 7 : 3. If 12% of the total profit is given to charity and A’s share is Tk. 3080, find the total profit.

Question: A and B share profits in the ratio 7 : 3. If 12% of the total profit is given to charity and A’s share is Tk. 3080, find the total profit.Solution:Lettotal profit = Tk. x∴ Remaining after charity = 88% of x = 22x/25ATQ,(22x/25) of (7/10) = 3080⇒ 154x/250 = 3080⇒ 154x = 3080 × 250⇒ x = (3080 × 250)/154∴ x = 5000∴ the total profit = Tk. 5000
