Question

by selling oranges at 32 for rs.10, a man loses 40%. how many oranges should he sell for rs. 10 if he should gain 20%?

Answer 1

let the cost price be ' x '

given,selling price of 32 oranges= Rs 10

loss = cost price - selling price

40 % x = x - 10

0.4 x = x - 10

0.6x = 10

x = Rs. 16.6 = cost price

cost of 32 oranges = Rs 16.6

20% of 16.66 = 0.2 ×16.6= Rs 3.32

new selling price to gain 20 % on 32 oranges should be

=16.6 + 3.32 = Rs 19.92

=appproximate Rs. 20 .

required number of oranges
to gain 20% for Rs 10=32/ 2=16 oranges

therefore, he should sell 16 oranges for Rs.10 to gain 20 %.
