Ravi has   two examinations on Wednesday – Engineering Mathematics in the morning and   Engineering Drawing in the afternoon. He has a fixed amount of time to read   the textbooks of both these subjects on Tuesday. During this time he can read   80 pages of Engineering Mathematics and 100 pages of Engineering Drawing.   Alternatively, he can also read 50 pages of Engineering Mathematics and 250   pages of Engineering Drawing. Assume that the amount of time it takes to read   one page of the textbook of either subject is constant. Ravi is confident   about Engineering Drawing and wants to devote full time to reading   Engineering Mathematics. The number of Engineering Mathematics text book   pages he can read on Tuesday is (a) 60 (b) 100 (c) 300 (d) 500
