5. 

The percentage of total number of qualified candidates to the total number of appeared candidates among all the five states in 1999 is?

[A]. 11.49%
[B]. 11.84%
[C]. 12.21%
[D]. 12.57%

Answer: Option B

Explanation:

Required percentage
= [ (850 + 920 + 890 + 980 + 1350) x 100 ] %
(7400 + 8450 + 7800 + 8700 + 9800)
= [ 4990 x 100 ] %
42150
= 11.84%.

How to add & divide in easy way?

1st way:

(4990) or 5000 approximately -2000 ~ 4800.

= 42150-2000~40000.

So 4800/40000*100 = 12 actual just less near 12 so answer = 11.84.

2nd way:

4.990/4.215*10 ~ 5/4.2*10 = 1/20/1/24 (using fraction) = 1.2*10 = 12%. So answer just less = 11.84.

How you have taken 4800 only as approximate?

Because nearest for 4990 is 5000. Can you please explain?

Please follow the below method.

i.e., 4990 = 5000 & 42150 = 42000.
Now, 5000/42000*100 = 11.90.
The nearest value is 11.84.
Hence, take that as an answer.

The value 840 is showed in the calculation but there is no such value in table similarly for value 7500.
