Answer:

30 students choose english ..

600 people were surveyed

Answer 2

1) The required "option A) 30" is correct.

2) The required "option C) 600" is correct.

Step-by-step explanation:

1. Given,

Total number of people in  surveyed = 500 and

The percentage of favorite English subject = 6 %

To find, total number of peope English as their favorite subject = ?

∴ 6 % of 500

= $\dfrac{6}{100} \times 500$

= 6 × 5 = 30

Thus, the required option A) 30 is correct.

2. Given,

Total number of people  math as their favorite subject = 270 and

The percentage of favorite English subject = 45 %

To find, total number of people in  surveyed = ?

∴ 45 % of x = 270

⇒ $\dfrac{45}{100}\times x=270$  

⇒ $x=\dfrac{270\times 100}{45}$

⇒ $x=\dfrac{30\times 100}{5}$

⇒ x = 30 × 20 = 600

Thus, the required "option C) 600" is correct.
