Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The number of girls in a class is 11 more than boys. If the students are divided into 3 groups equally, The number of boys in the class

a. 28

b. 31

C. 23

d. 25

EVALUATION

Let number of boys = x

Number of girls = x + 11

Total number of students

= x + x + 11

= 2x + 11

Now the students are divided into 3 groups equally

So 2x + 11 is divisible by 3

If x = 28 then 2x + 11 = 67 which is not divisible by 3

If x = 31 then 2x + 11 = 73 which is not divisible by 3

If x = 23 then 2x + 11 = 57 which is divisible by 3

If x = 25 then 2x + 11 = 61 which is not divisible by 3

Hence the required value of x = 23

FINAL ANSWER

Hence the correct option is c. 23
