Lets assume original regular price of sports jacket = x
On sale , price of jacket is reuced by 30%
Sales price = x - 30% 0f x
Sales price= x – 0.30x

That is
Sales price + k% of Sales price
= 0.70x + k% 0.70x
Also given after increasing to k% , price becomes equal to regular price
=> 0.70x + k% of 0.70x = original regular price
=>
=>
=>
=> 0.70k = 100 x 0.30
=>that is 43
Hence required value of k is 43% .
