Question

Lena is twice as old as Megha 10 year ago Lena was 7 times as old as Megha find their present age

Answer 1

megha age is 12 then put it in equation (1) we get=24
so lena age=24
megha=12
(in image i write x=6 by mistake its 24)

Answer 2

Let present age of megha be x

And present age of Lena be 2x

ATP,

7(x-10)=(2x-10)

7x-70=2x-10

7x-2x=-10+70

5x=60

x=12

Present age of Mehga is 12yrs

Present age of Lena is 2×12=24yrs
