C) 20 cm past the second lens..

1/v+1/u=1/f

initially u = 100cm f=50cms

so v = 50cms

this image will act as object for second lens.

so it is 90-50 = 40cms from lens

so now u=-40and f=-20

so v = -40

question should be a lens is placed 60cms beyond the first lens.

then u will be u=-10 f=-20

so from 1/v+1/u=1/f

v=20cms

so B) 20cms in front of second lens.

E.

B) 20 cm in front of the second lens..

C) 20 cm past the second lens.

because its just the same as of first lens.

B) 20 cm in front of the second lens..
