ANSWER

12 pens for Rs 36.5

STEP BY STEP EXPLANATION

Given total cost of 5 pens and 10 pencil = Rs 30

5 pens + 10 pencils = 30

pens + 2 pencils = 1

also given pen cost 3 more than a pencil

i.e, pen = 3 + pencil.

pen - pencil = 3

pens + 2 pencils = 6

-3 pencils = -3

pencils = 1

pen - 1 = 3

pen = 4

cost of pencils = 1 cost of pen = 4

So the answer is 12 pens for Rs 36.5
