Answer 1

The number of gel pens is 25 in the class.

Step-by-step explanation:

As given in question that students have 102 pens.

Which has some gel pens and the number of non-gel pens is two more than three times the number of gel pens.

Suppose the number of gel pens and non-gel pens is x and y respectively.

According to the question,

x + y = 102         ..............(i)

and y = 3x + 2

Put the value of non-gel pens in eq. (i)

x + 3x + 2 = 102

4x = 102 - 2

4x = 100

x = $\frac{100}{4}$

x = 25

Therefore, the number of gel pens is 25 in the class.
