Answer 1

Step-by-step explanation:

In a school there are 50 students in class 6- A

88℅ of the students passed a mathematics test

so 12% failed

the same number of boys and girls failed in the exam.

42℅ of the total students are girls

42℅ of the 50 students are girls

so [42/100*50]=21 girls

so 50-21=29 boys

88%0f 50

=44 students passed

we see that 6 failed

the same number of boys and girls failed in the exam.

so 6/2= 3 boys failed
