Question

There are 65 students in a science club. 40% of them bought a club T-Shirt with a picture of Albert Einstein. How many Einstein T-shirts were purchased?

A. 20
B. 24
C. 25
D. 26

Answer 1

So in order to solve the question, you must find out what is 40% (or 40/100) of 65 students. To do this you use the following equation:

65(students) X 40/100= number of students that bought a t-shirt.
26 students bought a t-shirt, so 26 shirts were purchased
ANSWER: D. 26

Answer 2

First, imagine that if there were 100 students in the science club in total, there would be 40 students who want to buy the T-shirt. That's what the number 40% tells us.
65 students in total* ( 40 students buying T-shirts/ 100 students in total)= 26 students buying T-shirts.
Note that students in total (in 65 students in total) and students in total (in 100 students in total) cancel out, and each student only buys one T-shirt.
Thus the final answer is D. 26
Hope this would help :))
