A man bought some fruits at the rate of 16 for Rs. 24 and sold them at the rate of 8 for Rs. 18. What is the profit per cent?

cp of 16 fruits =rs.24/-

so each fruit costs = 24 /16= 1.5/- per fruit

sp of 8 fruits= rs.18/-

so each fruit costs 18/8= 2.25/- per fruit

profit= sp-cp

=2.25-1.5

=0.75

25%

profit percentage is= 0.75 / 1.5 * 100 = 50 %
