Question

A fruit seller sells 30% of apples and still has 630 apples in the stock. how any apples had he bought

Answer 1

Hey!

Let the initial stock be 100x.

Apple's sold= 30% = 100x*30/100=30x.

Apple's left= 100x-30x=70x.

Also Apple's left = 630.

So 70x= 630.
x= 630/70=9.
100x= 100*9=900 Apple's.

The fruit seller had bought 900 apples.

Hope it helps.
