Directions (1-5): Study the following graph carefully to answer the questions that follow:
Distance (in km) travelled by five different trucks in a day
Q1. What is the ratio of the distance travelled by Truck A to the distance travelled by Track D?
Required ratio = 475:425 = 19:17
Q2. What is the average distance travelled by all trucks together?
(a) 510 km
(b) 515 km
(c) 425 km
(d) 475 km
Total distance covered by all the trucks = 2375 km
Average distance covered by all the trucks
= 2375/5 = 475
Q3. If Truck A covered the given distance at the average speed of 47.5 km/h, what was the time taken by it to cover this distance?
(a) 12 hours
(b) 10 hours
(c) 8 hours
(d) 6 hours
Total distance covered by A = 475 km
Time taken = 475/47.5 = 10 hours
Q4. The distance travelled by Truck E is approximately what percent of the total distance travelled by Track B and C together?
Total distance covered by E = 575 km
Total distance covered by B and C together
= 350 + 550 = 900 km
Required percentage = 575/900 × 100 = 64% = approx 62%
Q5. If the time taken by Truck C to cover the given distance was 8 hours, what was the average speed of the truck?
(a) 54.75 km/h
(b) 65.25 km/h
(c) 52.25 km/h
(d) 68.75 km/h
Required speed = 550/8 = 68.75 km/h
Directions (6-10): Study the following pie-chart and answer the questions given below:
Preferences of students of six beverages A, B, C,D, E and F in terms of degrees of angle in the pie-chart
Q6. What is the difference between the total number of students who prefer beverage A and C together and the total number of students who prefer beverage D and F together?
Difference of corresponding angles
= (122.4 + 21.6)° – (79.2 + 14.4)° = 50.4°
=> Required difference = 50.4/360 × 6800 = 952
Q7. What is the ratio of the number of students who prefer beverage F to the number of students who prefer beverage A?
Required ratio = 21.6 : 79.2 = 3 : 11
Q8. The number of students who prefer beverage E and F together is what percent of the total number of students?
Required percentage = ((64.8 + 21.6)/360) × 100 = 24%
Q9. The number of students who prefer beverage C is approximately what percent of the number of students who prefer beverage D?
Required percentage = 14.4/122.4 × 100 = 11.76 =approx 12%
Q10. How many students prefer beverage B and beverage E together?
Number of students who prefer beverages B and E together
