Solution

The correct option is A 37+43=80,80 pages
Number of pages in science magazine =37
37=3 Tens + 7 Ones
Number of pages in sports magazine =43
43=4 Tens +3 Ones
Total number of pages =37+43

37= 3 Tens + 7 Ones
43=+ 4 Tens + 3 Ones
--------------------------------
7 Tens + 10 Ones
7 Tens + 10 Ones =7 Tens + 1 Ten =8 Tens =80 pages

Hence, there are a total of 80 pages in both the magazines.
