Question
Person 'A' invests Rs. 'y' in a business, while person 'B'
contributes Rs. (y + 400). After a duration of 2 years, A's profit is 1/6 less than B's profit. Determine the value of 'y'.Solution
ATQ;
If both invest for the same period, profit ∝ investment
A's profit is 1/6 less than B's
A : B = (5/6) : 1 = 5 : 6
Hence, y : (y + 400) = 5 : 6
6y = 5(y + 400)
6y = 5y + 2000
y = 2000
