    Solution

    ATQ, Given:

    A invests ₹11,000 for 12 months = 11,000×12 = 132,000 C invests ₹13,000 for 12 months = 13,000×12 = 156,000 B invests Rs.'R' for 5 months = 5R Profit ratio is A : C : B = 5 : 5 : 2 Now, by using ratio of profit to set equation

    132,000 : 156,000 : 5R = 5 : 5 : 2 Make A and C equal to match 5:5 = adjust C to 132,000 Now:

    132,000:132,000:5R = 5:5:2 = 5R/132,000 = 2/5 5R = 2/5 × 132000 = 52,800 R = 10,560 Therefore, B should invest ₹10,560 to get a 2-part
