Answer 1

Correct Answer - Option 2 : 42

Given:

In a classroom, the number of boys is three times the number of girls

Let us assume that the number of girls is = G students

Now, The number of boys will be = 3G students

Calculation:

Now the Total number of students in a classroom will be = sum of the boys and the girls = 3G + G = 4G

⇒ Check from the option which is not the multiple of 4

∴ Only 42 is not the multiple of 4
