answer is the 50%
25% percent less equals to the 50% more which means initially assumed number of pens to the number of pencils is 1:2
now assume any numbers increase them as said in the question and you will get the answer.

Pre decides no of pens and pencils: p+Q
No he bought: 1.5p + 0.75q
Given both are equal, so 0.5p = 0.25q. P/q= 1/2. Assume the p = 100, q = 200 . Then just add 16.66 and 66.66 you will get 450. Which is 150 more than the initial assumed 300 (100+200). So the answer is 50%
