A fruit seller purchased 20 kg of apples at Rs 50 per kg. Out of these, 5% of the apples were found to be rotten. If he sells the remaining apples at Rs 60 per kg, then his _is _%.

Class 7th NCERT - Exemplar Mathematics 7. Comparing Quantities

Answer :

Given seller purchased apples at 50 per kg

Total purchased apples = 20kg

⇒ Since, 5% were rotten, so good apples = 20 – 5% of 20kg (rotten)

= 20-

= 20-1

= 19kg

⇒ 19kg apples are sold at 60 per kg

∴ total sp = 19 × 60

= 1140

∴ CP was 20kg apples = 20 × 50 = 1000

∴ Profit = SP-CP = 1140-1000

= 140

⇒ Profit% =

=

=

= 14%
