Question

8%of apples of fruits seller get rotten. After selling 80%of good apples he has 92 good apples left. Initially the number of apples was?

Answer 1

Let the initial number of apples be x ,then

apples that are good= x - 8% of x

= x - 8/100× x

=92x/100

Now , 80% of good apples were sold that means 20% of apples were unsold

So, 20 % of good apples =92

= 20/100 × 92x/100 = 92

= x = 92 × 100 × 100 / 20× 92

= x = 10000/20

By solving it the value of x comes to be 500

So , initially the number of apples was 500

Hope it helps...
