Question

The sum of shika’s and Ravi’s present age is 73.four years from now Shika’s age will be twice Ravi’s age . Find their present ages

Answer 1

Shika, s age = 2x , Ravi age =x

atq

x+4+2x+4= 3x + 8

73-8=3x

65=3x

x==65/3

x=21.666

Answer 2

Answer:

let shika's age be x

and ravi's be y

it is give x+y=73

x=73-y        (1)

after 4 years  add 4 to both sides

y+4=2x+4

now we have to solve this equation

y=2(73-y)+4-4

y=146-2y

3y=144

y=144/3

y=48 years

ravi's age is 48 years

now shika's age is

x+y=73

x+48=73

x=73-48

x=25 years

so shika's age is 25 years

and ravi's age is 48 years

hope it helps
