[A]. 12.36%
[B]. 12.16%

Answer: Option D

Explanation:

Required percentage
= [ (840 + 1050 + 920 + 980 + 1020) x 100 ] %
(7500 + 9200 + 8450 + 9200 + 8800)
= [ 4810 x 100 ] %
43150
= 11.15%

Assume 10% of 43150 i.e., 4315.

4810 - 4315 = 495.

1% of 43150 is 431.50.
495-431.50 = 63.50.

63.50 is 0.15% of 43150.

Then add all 10%+1%+0.15% = 11.15%.

Try to consider the denominator parts as 1% , 10% to solve these kind of problems.

I think we can do the below:

4810/4315 = .48/.432(apprx) = .12/.108 = .03/.27 = .01/.09 = 1/9 = 100/9% = 11.111...%

4810/43150*100 = 11.147 this is correct answer.
Why should you given the answer - 11.15?

Please reply me.

@Kapil, As you said exact value is 11.147 only but we have nearest value 11.15 in the options. You have to consider the most nearest value when there is no exact value.

4810---->4500.

43150---->40000.

4500/40000*100 = 11.25%.

So nearest value off our answer in options was 11.15%.

So the answer is D.

@Swathi.

Your calculation is wrong, it goes beyond 13% so, how we can get answer between 11.15 and 11.47%.

Please correct me if I m wrong. Thanks.
