Directions—(Q. 1–5) Study the following graph carefully to answer the questions that follow—
The following line graph gives distance (in km) travelled by five different trucks in a day.
Q1. What is the respective ratio of the distance travelled by Truck A to the distance travelled by Truck D?
(1) 17 : 19
(2) 11 : 15
(3) 19 : 17
(4) 15 : 11
(5) None of these
Q2. What is the average distance travelled by all the Trucks together ?
(1) 510 km
(2) 515 km
(3) 425 km
(4) 475 km
(5) None of these
Q3. If Truck C covered the given distance at the average speed of 55 km/hr, what was the time taken by it to cover this distance?
(1) 12 hours
(2) 10 hours
(3) 8 hours
(4) 6 hours
(5) None of these
Q4. The distance travelled by Truck A is approximately what per cent of the total distance travelled by Truck E and C together ?
(1) 44
(2) 50
(3) 52
(4) 58
(5) 55
Q5. If the time taken by Truck B to cover the given distance was 8 hours, what was the average speed of the truck ?
(1) 51·75 km/hr
(2) 45·25 km/hr
(3) 52·25 km/hr
(4) 43·75 km/hr
(5) None of these
Answer & Explanation 1. (3) Required ratio = 475 : 425 = 19 : 17 2. (5) Total distance travelled by all trucks = 475 + 350 + 550 + 425 + 525 = 2325 km Average distance = 2325/5 = 465 km . 3. (2) Time taken by truck C = 550/55 = 10 hours. 4. (1) Required percentage =( 475)/ ( 550 + 525) ] X 100 = 44% ( approx) 5 . (4) Speed of truck B = 350/8 = 43.75 km/hr
