Question

Peggy was taking a timed 70-question test. She was able to correctly answer 80% of the questions but had to skip the rest. How many questions did Peggy answer correctly? A. 24 B. 46 C. 14 D. 56

Answer 1

D. 56

Explanation:

80% can also be said as 80/100 and then multiply that with the total value of the thing you need to find.

So in this case its 70.

Now 70x(80/100) [remember the BODMAS rule] solve the bracket first.

80/100 = .8 x 70 = 56

hence the option D

Answer 2

D

Explanation:

(my trick to calculate percentage) to calculate 1% of 70 we do 70/100= 0.7, then we multiply 0.7 with the percent which is 80, so 0.7*80=56

therefor the answer is 56!
