1. Study the following table carefully and answer the question that follow:
Number of candidates (in lakhs) appearing in a Entrance Examination from six different Cities.

City A B C D E F

No. of Candidates 1.25 3.14 1.08 2.27 1.85 2.73

Ratio of Candidates Passing and Failing Within the City

City Ratio of Passing and Failing

A 7 : 3

B 5 : 3

C 4 : 5

D 1 : 3

E 3 : 2

F 7 : 5

The number of candidates appearing for the exam from City C is what per cent of the number of candidates appearing for the exam from City B? (rounded to nearest integer)

A. 27%

B. 34%

C. 42%

D. 21%

Solution:

\begin{aligned} No. of candidates from city C \\ = 1.08 \times 100000 \\ = 108000 \\ No. of candidates from city B \\ = 3.14 \times 100000 \\ = 314000 \\ ∴ Required percentage \\ = (\frac{108000}{314000} \times 100) % \\ = (\frac{108}{314} \times 100) % \\ = (\frac{54}{157} \times 100) % \\ = \frac{5400}{157} % \\ = 34.39 % \\ \approx 34 % \end{aligned}

City	Ratio of Passing and Failing
A	7 : 3
B	5 : 3
C	4 : 5
D	1 : 3
E	3 : 2
F	7 : 5
