    B ₹2,200 Correct Answer Incorrect Answer
    C ₹2,400 Correct Answer Incorrect Answer
    D ₹1,600 Correct Answer Incorrect Answer

    Solution

    Let ₹x be the amount lent at 8%.
    Then, ₹(4000 - x) is lent at 10%.

    Simple interest for 1 year: 8x/100 + 10(4000 - x)/100 = 352

    8 x  +  40000  −  10 x  =  35200 

    ⇒  − 2 x  =  −  4800

    ⇒ x  =  2400

    Amount lent at 10% = 4000 - 2400 = ₹1600.
