Question

Shashi age arvind age 3 : 4 if arvind 28 year old find the shashi's age?

Answer 1

Step-by-step explanation:

let shashi age 3x years

and arvind's age 4x years

if arvind is 28 years old then it means 4x=28

x=28÷4=7

so the value of x will be 7

then shashi age 3x=3×7=21

so shashi age is 21 year

Answer 2

Answer:

Given

• Shashi age : Arvind age

=3:4

• Arvind is 28 years

this mean

Shashi age/Arvind age

=3/4

let shashi age is x

then x/28 = 3/4 (do cross multiplication)

4x= 3 X 28

x= 84/4

x=21

hence shashi age is 21 years
