Sample Question

Directions: Study the following pie chart and answer the questions that follows:

Total Number of Teachers = 6400

(Uttar Bihar Gramin Bank 2012)

Question 1: If one-thirty sixth of the number of teachers from university F is professors and the salary of each professor is Rs 96000, what will be the total salary of all the professors together from university F?

[1] Rs 307.2 lakh
[2] 32.64 lakh
[3] Rs 3.072 lakh
[4] 3.264 lakh
[5] None of these

Solution:-

Number of teachers from university F = 18% of 6400 = 1152
1/36 of 1152 = 32
Total salary = 32*96000 = 3072000 = 30.72 lakh. Answer [5] is correct. (Note the tricky options [1] and [2])

Short Tricks:-

Total salary = (6400*18*1*96000)/100*36 = 30.72 Lakhs

Question 2: Difference between the total number of teachers in university A, B and C together and the total number of teachers in university D, E and F together is exactly equal to the number of teachers in which university?

[1] A
[2] B
[3] C
[4] D
[5] F

(You don’t even have to calculate the number of teachers. Just presence of mind is needed.)

Solution:-

Number of teachers in university A, B and C = 11+17+19 = 47%
Number of teachers in university D, E and F = 6+29+18 = 53%
Difference = 6% = University D. Answer [4] is correct.

Question 3: What is the average of teachers in university A, C, D and F together?

[1] 854
[2] 3546
[3] 3456
[4] 874
[5] None of these

Solution:-

Again, solving it quickly.

11+19+6+18 = 54%. Average = 54/4 % = [54/400]*6400 = 54*16 = 864. Answer [5] is correct.

Question 4: If twenty five percent of the number of teachers in university C is female, what is the number of male teachers in university C?

[1] 922
[2] 911
[3] 924
[4] 912
[5] None of these

Solution:-

Number of teachers in university C = 19% of 6400 = 19*64 = 1216
25% of this is female. Hence remaining 75% is male.
Number of male teachers = 75% of 1216 = [3/4]*1216 = 912. Option [4] is correct.

Short Tricks:-

Number of male teachers = (6400*19*75)/100*100 = 912

Question 5: Number of teachers in university B is approximately what percent of the total number of teachers in university D and E together?

[1] 55%
[2] 59%
[3] 49%
[4] 45%
[5] 65%

Solution:-

Short Tricks:-

Just solve the percentages.
University B = 17%. University D+E = 6+29 = 35%
Required percentage = [17/35]*100 = approx. 49%. Answer is [3]
