bro in 2nd step
it is given that focal length is 50 and you write 40 as a focal length
bro the general formula for find the position of image is 1/f =1/v -1/u
how you drive this formula
that you use in solving questions
Sorry for the second step...
General formula ko use krke he derive kiya hai.....general formula se 1/ v ki value nikal lo aur m=v/u(magnification in case of lens) me put krdo....
