₹4,80,000 was collected for a school building. The first donor gave 35% of it, the second gave ₹1,20,000 and the third gave the rest. The third donor's gift is what per cent more than the second donor's?

First = 35% of 4,80,000 = ₹1,68,000. Third = 4,80,000 - 1,68,000 - 1,20,000 = ₹1,92,000. The words 'more than the second' fix ₹1,20,000 as the base: (192000 - 120000)/120000 = 72/120 = 0.60 = 60%. 37.5% is 72000/192000 - the same gap read against the third donor's gift, which answers 'the second is how much less than the third'. 40% is the third donor's share of the whole fund. 15% is the gap between their shares of the fund (40% and 25%) in percentage points.
