Answer 1

Answer:

Q21. Let the no. of girls=x

so, the no. of boys= 2x/5

Total students= 42

ATQ (according to the question)

x + 2x/5 = 42

5x+2x/5 = 42

7x/5 = 42

7x = 42*5

7x = 210

x = 210/7

x = 30

NO. OF BOYS= 30

NO. OF GIRLS= 42-30 = 12

Answer 2

24) 15 sides

Step-by-step explanation:

22)

let kumar's age be x

4x+5=49

4x=49-5

4x=44

x=44/4

x=11

so, kumar's age =11

23 number is in pic

24)

Sum of all exterior angle of a regula polyogon = 360 degree

Measure of each exterior angle = 24 degree

No. of sides = 360/24 = 15

so, the no. of sides are 15
