‘A’ and ‘B’ started a business by investing Rs. ‘b’ and Rs. ‘b + 400’, respectively. If 9 months later the ratio of profit shares of ‘A’ and ‘B’ was 7:8, respectively, then find the amount (initially) invested by ‘B’.
ATQ; [(9 × b)/{(b + 400) × 9}] = (7/8) Or, (9b × 8) = 63 × (b + 400) Or, 72b = 63b + 25200 Or, 9b = 25200 So, b = 2800 So, initial investment made by ‘B’ = 2800 + 400 = Rs. 3,200
