Question
Person 'M' invests Rs. 'a' in a business, while person
'N' contributes Rs. (a + 600). After a duration of 2 years, M's profit is 1/3 less than N's profit. Determine the value of 'a'.Solution
ATQ;
If both invest for the same period, profit ∝ investment
M's profit is 1/3 less than N's
M : N = (2/3) : 1 = 2 : 3
Hence, a : (a + 600) = 2 : 3
3a = 2(a + 600)
3a = 2a + 1200
a = 1200
