Question

The value of \(\frac {1.331 \times 21.9 \times 1.24}{16.5 \times 0.121 \times 7.3 \times 0.62} \times \frac {2.8 \times 1. {36}}{27. {2}}\) is:
1. 0.24
2. 0.36
3. 0.56
4. 0.18

Answer 1

Correct Answer - Option 3 : 0.56

Concept:

This type of question can be solved by the help of BODMAS

Follow BODMAS rule to solve this question, as per the order given below

Step – 1: Parts of an equation enclosed in ‘Brackets’ must be solved first and, in the bracket,

Step – 2: Any mathematical ‘Of’ or ‘Exponent’ must be solved next,

Step – 3: Next, the parts of the equation that contain ‘Division’ and ‘Multiplication’ are calculated,

Step – 4: Last but not least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated.

Calculation:

\(\frac {1.331 × 21.9 × 1.24}{16.5 × 0.121 × 7.3 × 0.62} × \frac {2.8 × 1. {36}}{27. {2}}\)

⇒ (11 × 3 × 2 × 10)/(165) × 0.14

⇒ 4 × 0.14

⇒ 0.56

∴ The required answer is 0.56.
