    Sir ,actually reading from u-v graph of convex lens comes is 15.75 cm,from calculation it is about 15.625cm but from 1/u and 1/v graph it is 22.7 cm. So sir when examiner see the reading did it not say that your reading from u-v and calculation is right but your reading from 1/u and 1/v graph is very different i.e.22.7 cm ,sir how I tackle this question,because rough focal length of convex lens is 15cm.
