Question
Person 'X' invests Rs. 'z' in a business, while person
'Y' contributes Rs. (z + 250). After a duration of 2 years, X's profit is 1/4 less than Y's profit. Determine the value of 'z'.Solution
ATQ;
If both invest for the same period, profit ∝ investment
X's profit is 1/4 less than Y's
X : Y = (3/4) : 1 = 3 : 4
Hence, z : (z + 250) = 3 : 4
4z = 3(z + 250)
4z = 3z + 750
z = 750
