Question

Match the following with their square roots.

$\begin{array}{cc}Numbers& Squareroots\\ 1.289& a.22\\ 2.1225& b.17\\ 3.196& c.35\\ 4.484& d.14\end{array}$

• A. 1-b, 2-d, 3-c, 4-a
• B. 1-b, 2-c, 3-d, 4-a
• C. 1-c, 2-b, 3-d, 4-a
• D. 1-b, 2-c, 3-a, 4-d

Answer 1

The correct option is B

1-b, 2-c, 3-d, 4-a

This can be solved without actually calculating the square roots. Arranging the given numbers in ascending order.

Numbers:- 196 < 289 < 484 < 1225

Square roots:- 14 < 17 < 22 < 35

So,$\sqrt{196}$ = 14; $\sqrt{289}$ = 17; $\sqrt{484}$ = 22 and $\sqrt{1225}$ = 35.
