Directions: Study the following graph carefully and answer the questions given below it.

Number of tourists visiting a country from city A and city B during six different months.

1. What is the difference between average number of tourists from city A and city B during all the months together?

1. 30
2. 38
3. 40
4. 42

Solution: Average number of tourists in city A, $$= \frac{300 + 400 + 450 + 500 + 500 + 400}{6}$$ $$= \frac{2550}{6} = 425$$ average number of tourists in city B, $$= \frac{250 + 500 + 500 + 600 + 450 + 500}{6}$$ $$= \frac{2800}{6}$$ $$= 466.67 \approx 467$$ Hence, the required difference, $$= 467 - 425 = 42$$

1. What is the respective ratio between the total number of tourists from city A and B during January, Fabruary and March taken together?

1. 24:25
2. 23:24
3. 23:25
4. 24:22

Solution: Tourists from city A during January, Fabruary and March taken together, $$= 300 + 400 + 450$$ $$= 1150$$ Tourists from city B during January, Fabruary and March taken together, $$= 250 + 500 + 500$$ $$= 1250$$ Hence, required ratio, $$= 1150 : 1250$$ $$= 23 : 25$$

1. By what percent is the number of tourists from city A less than that from city B in the month of April?

1. 10%
2. 20%
3. 30%
4. 40%

Solution: Required percent, $$= \frac{600 - 500}{500} \times 100$$ $$= 20 \ \%$$

1. By what percent the number of tourists from city B increased in April than that from the month January?

1. 140%
2. 120%
3. 100%
4. 75%

Solution: Required percent, $$= \frac{600 - 250}{250} \times 100$$ $$= 140 \ \%$$

1. By what percent approximately is the total number of tourists from city A less than that of all the tourists from city B taking all the months together?

1. 5%
2. 7%
3. 8%
4. 9%

Required percent, $$= \frac{2800 - 2550}{2800} \times 100$$ $$= 8.92 \ \% \approx 9 \ \%$$
