The value of $\sqrt{0.01}+\sqrt{0.81}+\sqrt{1.21}+\sqrt{0.0009}$ is:


A) 2.13

B) 2.23

C) 2.02

D) 3.01

Answer:

Option A

Explanation:

Given exp = $\sqrt{\frac{1}{100}}+\sqrt{\frac{81}{100}}+\sqrt{\frac{121}{100}}+\sqrt{\frac{9}{10000}}  =$

$\frac{1}{10}+\frac{9}{10}+\frac{11}{10}+\frac{3}{100}$

$0.1+0.9+1.1+0.03 = 2.13$
