Answer:

rakhis age is 10

rakhis mother age is 40

Step-by-step explanation:

Rakhi's mother age = x years

Rakhi's age = y years

First condition:

Rakhi's mother is four time as old as rakhi.

that means,

x=4y------(1)

After 5 years

Rakhi's mother age = (x+5) years

Rakhi's age =(y+5) years

second condition:

Rakhi's mother is three time as old as her

that means

x+5 = 3 (y+5)

x+5 = 3y+15

x-3y=10--------(2)

put equation (1) in equation (2)

therefore,

4y-3y= 10

i.e, y=10

now put y=10 in equation (1)

we get

x= 40

Given:

Rakhis age is 10

Rakhis mother age is 40

Explanation:

Rakhi's mother age = x years

Rakhi's age = y years

First condition:

Rakhi's mother is four time as old as rakhi.

that means,

x=4y------(1)

After 5 years

Rakhi's mother age = (x+5) years

Rakhi's age =(y+5) years

second condition:

Rakhi's mother is three time as old as her

that means

x+5 = 3 (y+5)

x+5 = 3y+15

x-3y=10--------(2)

put equation (1) in equation (2)

therefore,

4y-3y= 10

i.e, y=10

now put y=10 in equation (1)

Hence

x= 40

Hope this helps !
