The number of questions in set 1 is approximately how much percent less than the number of questions in set 4?
1. 14.9 percent
2. 10.9 percent
3. 0.169
4. 12.9 percent

Answer 1

Correct Answer - Option 4 : 12.9 percent

Given:

The number of questions in set 1 = 54

The number of questions in set 4 = 62

Calculation:

Let the number of questions in set 1 be x less than the number of questions in set 4.

According to the question, 

x = 62 - 54

⇒ 8

Now, Required percentage = (8/62) × 100%

⇒ (400/31)%

⇒ 12.903%

∴ The number of questions in set 1 is approximately 12.9% less than the number of questions in set 4.
