Question

A vendor bought bananas at 6 for rs.10 and sold them at rs.4 for rs.6 .find his gain or loss percent .

Answer 1

hope so loss percent is 6.25

Answer 2

To avoid fractions , let the number of bananas bought and sold be the LCM of 10 and 6 ie 30

CP of 30 bananas = 30 * 10 / 6

= 50

SP of 30 bananas = 30 * 6 / 4

= 45

Loss = 50 - 45

= 5

% loss = 5*100 / 50

= 10%
