    Solution

    ATQ, Simple interest = (Sum ├Ч rate of interest ├Ч time period in years) ├╖ 100 So, interest earned from first investment = (r + 5000) ├Ч 12 ├Ч 4 ├╖ 100 = Rs. (r + 5000) ├Ч (12/25) And, interest earned from second investment = (r - 5000) ├Ч 12 ├Ч 3 ├╖ 100 = (r - 5000) ├Ч (9/25) So, (r + 5000) ├Ч (12/25) - (r - 5000) ├Ч (9/25) = 0.4r Or, 12 ├Ч (r + 5000) - 9 ├Ч (r - 5000) = 10r Or, 12r + 60000 - 9r + 45000 = 10r Or, 105000 = 7r So, r = 15000
