Question

* A man bought a certain number of oranges,
out of which 13 percent were found rotten. He
gave 75% of the remaining in charity and still
has 522 oranges left. Find how many had he
bought?​

Answer 1

Step-by-step explanation:

Let the number of oranges he first bought =x

Since 13/% were rotten, 100−13=87% of the oranges are good.

Since he gave 75% of this remaining 87% good oranges, the number of oranges he will still have will be 25% of the remaining 87% good oranges.

Given,

25% of 87% of x=522

=>

100

25

×

100

87

×x=522

=>x=2400

Hence, the man had bought 2400 oranges first.
