√[(1.21 × 0.9)/(1.1 × 0.11)] = ?

1. 3
2. 6
3. 9
4. 5

Answer 1

Correct Answer - Option 1 : 3

Given:

√[(1.21 × 0.9)/(1.1 × 0.11)]

Calculations:

According to the question, we have

√[(1.21 × 0.9)/(1.1 × 0.11)]

⇒ √[(121 × 9)/(11 × 11)]

⇒ √(121 × 9)/121

⇒ √9

⇒ 3

∴ The value of √[(1.21 × 0.9)/(1.1 × 0.11)] is 3.
