Answer 1

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.
