Question

Which among the following numbers is the greatest?
$0.07+\sqrt{0.16},\sqrt{1.44},1.2\times 0.83,1.02-\frac{0.6}{24}$

• A. $\sqrt{1.44}$
• B. $0.07+\sqrt{0.16}$
• C. $1.2\times 0.83$
• D. $1.02-\frac{0.6}{24}$

Answer 1

The correct option is A $\sqrt{1.44}$

$\Rightarrow 0.07+\sqrt{0.16}=0.07+0.4=0.47$

$\Rightarrow \sqrt{1.44}=1.2$

$\Rightarrow 1.2\times 0.83=0.996$

$\Rightarrow 1.02-\frac{0.6}{24}=1.02-\frac{6}{240}=1.02-0.025=0.995$

$\therefore$ The greatest number is $1.2$ i.e. $\sqrt{1.44}$
