**The number of students appearing for a college admission test from various cities (in millions).**

- The number of students appearing for the college admission test from city S is approximately what percent of the number of students appearing for the test from city R?
- 140 %
- 120 %
- 110 %
- 100 %

Answer: (a) 140 %

Solution: Required percentage $$ = \left[\frac{7}{5} \times 100\right] \ \% $$ $$ = 140 \ \% $$

Solution: Required percentage $$ = \left[\frac{7}{5} \times 100\right] \ \% $$ $$ = 140 \ \% $$

- What is the ratio of the number of students appearing for the college admission test from city T to that of city U?
- 3 : 7
- 4 : 5
- 5 : 7
- 7 : 8

Answer: (d) 7 : 8

Solution: Required ratio $$ = \frac{7}{8} $$ $$ = 7 : 8 $$

Solution: Required ratio $$ = \frac{7}{8} $$ $$ = 7 : 8 $$

- The number of students appearing for the college admission test from city U is approximately what percent of the total number of students appearing for the college admission test from all the cities together?
- 21 %
- 25 %
- 29 %
- 32 %

Answer: (a) 21 %

Solution: Required percentage $$ = \left[\frac{8}{38} \times 100\right] \ \% $$ $$ = 21.052 \ \% $$ $$ \approx 21 \ \% $$

Solution: Required percentage $$ = \left[\frac{8}{38} \times 100\right] \ \% $$ $$ = 21.052 \ \% $$ $$ \approx 21 \ \% $$

- What is the average number of students appearing for the college admission test from all the cities together?
- 3.52 million
- 4.67 million
- 4.81 million
- 6.34 million

Answer: (d) 6.34 million

Solution: Required average $$ = \frac{38}{6} $$ $$ = 6.34 \ million $$

Solution: Required average $$ = \frac{38}{6} $$ $$ = 6.34 \ million $$

- What is the ratio of the number of students appearing for the college admission test from the cities P, Q, and S together to the number of students appearing for the test from the cities R, T, and U together?
- 7 : 8
- 9 : 10
- 11 : 12
- 11 : 13

Answer: (b) 9 : 10

Solution: Required ratio $$ = \frac{18}{20} $$ $$ = 9 : 10 $$

Solution: Required ratio $$ = \frac{18}{20} $$ $$ = 9 : 10 $$
