C Correct answer
Explanation

Interest from B = 25000 * 0.07 * 4 = 7000. Total interest = 11200. Interest from C = 11200 - 7000 = 4200. 4200 = P * 0.07 * 4 = P * 0.28. P = 4200 / 0.28 = 15000.

AI explanation

The Simple Interest formula states that Interest equals (Principal multiplied by Rate multiplied by Time) divided by 100. Using this, the interest from B is (25000 multiplied by 7 multiplied by 4) divided by 100, which equals Rs 7,000. The total interest received is Rs 11,200, so the interest from C is 11,200 minus 7,000, which is Rs 4,200. Applying the Simple Interest formula again for C, 4200 equals (Principal multiplied by 7 multiplied by 4) divided by 100, meaning the principal lent to C is Rs 15,000.
