Number of Questions 2 5
Time (in minutes) 9 ?


How much time does it take to complete 5 questions?
11 minutes, 30 seconds
22 minutes, 30 seconds
3 minutes
12 minutes

Answer 1

The time taken to complete 5 questions is (option b) 22 minutes, 30 seconds

Given,

The number of questions = 2

Time taken to complete 2 questions = 9 minutes

Now,

The number of questions = 5

We have to find the time taken to complete 5 questions:

We can consider ratio here:

That is,

Number of questions : Time taken to complete

So,

2 : 9 and 5 : x

Lets equate:

2 : 9 = 5 : x

That is,

2x = 5 × 9

Now, divide 2 on both sides:

2x/2 = (5 × 9) / 2

Here,

x = 45/2

Then,

x = 22.5

Converting this into minutes, we get 22 minutes, 30 seconds.

That is,

The time taken to complete 5 questions is (option b) 22 minutes, 30 seconds
