Answer:

Let the age of Karthik be ' x ' years and the age of Radha be y years..

According to the first condition...

x- 5 = 2( y - 5)

x - 5 = 2y - 10

x - 2y = -10+5

x - 2y = -5 ------ equation 1

Second condition

x + 10 = 3(y + 10)

x + 10 = 3y + 30

x - 3y = 30 - 10

x - 3y = 20 ------ equation 2

Solving 1 and 2

x - 3y = 20

x - 2y = -5

- + +

---------------

y = 25

substitute the value of y = 25 in

equation 2

x - 3y = 20

x - 3(25) = 20

x - 75 = 20

x = 20 + 75

x = 95

So the age of Karthik is x = 95 and the age of Radha is y = 25

❣️ Thank you for asking the question ❣️

Answer:

age of Karthik = 35 years, age of Radha = 20 years

Step-by-step explanation:

let the present age of Karthik be x and Radha be y years old.

according to the question,

x-5 = 2(y-5)

=> x-2y = -5 ............(1)

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

=> 2x-3y = 30-20= 10

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

from eqn (1) and (2)

=> - y = -20

=> y = 20 years

substituting in (1)

x-2×20= -5

=> x= -5+40

=> x= 35 years
