Indian Economy - Understanding the basics of Indian economic system

Pencils, Pens and Exercise books in a shop are in the ratio of 10: 2 : 3. If there are 120 pencils, the number of exercise books in the shop is:

Let Pencils = 10x,

Pens = 2x

Exercise books = 3x.

Now, 10x = 120

hence x = 12.
Number of exercise books = 3x = 36.

Hence, option 2 is the correct answer.
