Line Diagram 39

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
