    to disaster relief, 20% of the rest to a local NGO, and 10% of what was then left for a school. How much money is he left with?

    Solution

    ATQ,

    Contribution to disaster relief = 0.18 × 30000 = Rs. 5,400

    Amount left = 30000 – 5400 = Rs. 24,600

    Donation to NGO = 0.20 × 24600 = Rs. 4,920

    Amount left = 24600 – 4920 = Rs. 19,680

    Donation to school = 0.10 × 19680 = Rs. 1,968

    Final remaining amount = 19680 – 1968 = Rs. 17,712
