suppose
Age of sona= x
" "her mother= 4x
after 5 year (5 year add
(x+5) =(4x +5)
her mother age will be three times oldas sona.
3 (x+5) = (4x +5)
3x+15 = 4x +5
3x -4x=5 -15
-x =-10
x =10
ans= age of sona= 10 year
age of her mother= 10x4=40 year
Age of sona= x
" "her mother= 4x
after 5 year (5 year add
(x+5) =(4x +5)
her mother age will be three times oldas sona.
3 (x+5) = (4x +5)
3x+15 = 4x +5
3x -4x=5 -15
