Question

Arrange the following with increasing order of their values from top to bottom.

• A. $4\times 3$
• B. 3+3+3+3+3+3
• C. $12\times 11$
• D. $3\times 16$

Answer 1

$4\times 3=123+3+3+3+3=3\times 5=15$

$112\underset{–}{\times 11}22\underset{–}{110}\underset{–}{132}$
$\text{So,}12\times 11=132$

$116\underset{–}{\times 3}\underset{–}{48}$
$\text{So,}16\times 3=48$

Now clearly, 12 < 15 < 48 < 132.
