ATQ, Ratio of profit share of Chintu and Jimmy respectively = [(3a - 200) × 8]:[(4a - 400) × 20] = (6a - 400) :(20a - 2000) ATQ, (6a - 400) :(20a - 2000) = (5,940 - 4,500) :4,500 Or, (3a - 200) ÷ (10a - 1000) = (8/25) Or, 25 × (3a - 200) = 8 × (10a - 1,000) Or, 75a - 5,000 = 80a - 8,000 Or, 5a = 3,000 So, 'a' = 600 Therefore, amount invested by Jimmy = (4a - 400) = 4 × 600 - 400 = Rs. 2,000
