Krishan invested a sum of ₹25,000 in two parts. He earned 11% p.a. simple interest on part 1 and 10% p.a. compound interest compounded annually on part 2. If the total interest received by him after 2 years is ₹5,370, then find the sum invested on simple interest.
The value of \(18\frac{2}{11} \div \left[ \frac{7}{33} + \left\{ \frac{29}{6} - \frac{3}{11} \times \left( 5\frac{1}{6} - 3\frac{1}{3} \right) \right\} \right]\)
