Two years ago, a survey showed that 2400 students of a college were able to use computers at home. According to this year's survey, there has been a 30% increase in the number of students who are able to use computers at home. How many students are able to use computers at home now?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3120.
Number of students 2 years ago = 2400
Increase in students = 30%
⇒ 30% of 2400 = 30/100 × 2400 = 720
Add increase to original number = 2400 + 720 = 3120
