Answer 1

Step-by-step explanation:

Solution for question 2 :

Let Rajni's age be x years

Now according to the question his father's age now is 10 + 2x years

Also given : Her father age = 58 years

Now to find age of Rajni we have ,

10 + 2x = 58

2x = 48

x = 48/2

x = 24 years

Solution for question 4 :

Let the number of total boys in the school be x

Total number of students in the school = 450

Total number of girls = 60 + x

Total number of students = 450

60 + x + x = 450

2x = 450 - 60

2x = 390

x = 390/2

x = 195

Number of boys = 195

Number of girls = 195 + 60 = 255
