    Question

    ‘Nikhil’ and ‘Amit’ started a firm with investments

    of Rs. 2,800 and Rs. 4,200 respectively. After 16 months, Nikhil increased his amount by 25%, and Amit reduced his by Rs. 1,000. If they made Rs. 8,000 profit in 3 years, what’s the difference in their shares?
    A Rs.800 Correct Answer Incorrect Answer
    B Rs.520 Correct Answer Incorrect Answer
    C Rs.456 Correct Answer Incorrect Answer
    D Rs.700 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Increased investment of ‘Nikhil’ = 2800 × 1.25 = Rs. 3,500

    Decreased investment of ‘Amit’ = 4200 – 1000 = Rs. 3,200

    Ratio = (2800 × 16 + 3500 × 20):(4200 × 16 + 3200 × 20) = 134.0:150.4 = 335:376

    Difference = 8000 × {(376 – 335) ÷ (376 + 335)} = Rs. 456
