Pg 316 of book T.R. Jain and V.K. Ohri question no. 2, second last step 11.5 - 4.5 / 11.5 + 4.5 must give the answer 7/16 instead of 7/76 and then the answer should be equal to 0.437.

Thanks Sarabjeet. The concerned error is merely a typo. The solution is absolutely correct. In the denominator it should be 16 instead of 76.
