Directions—(Q. 1–5) Study the following graph carefully to answer the questions—
The following Bar graph gives the number of products manufactured and sold by a company over the years. (in thousands)
1. What is the average number of products manufactured by the company over all the years together ?
Required average = (35000 + 37500 + 42500 + 45000 + 47500 + 52500)/6 =43330 (approx).
2. The number of products sold by the company in the year 2004 is what per cent of the number of products manufactured by it in that year ? (Rounded off to two digits after decimal)
Required percentage =( 25/35) X 100 = 71.43 %
3. What is the per cent increase in the number of products manufactured by the company in the year 2006 from the previous year ? (Rounded off to two digits after decimal)
Required percentage = [( 42.5 – 37.5)/(37.5)]X 100= 13.33 %
4. What is the respective ratio of the number of products not sold by the company in the year 2007 to those not sold in the year 2005 ?
Required ratio = (45 – 42.5) : (37.5 – 30) = 1 : 3
5. What is the difference in the number of products manufactured by the Company in the year 2009 and 2008 ?
Difference = 52500 – 47500 = 5000
Directions—(Q. 6–10) 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.
6. What is the respective ratio of the distance travelled by Truck A to the distance travelled by Truck D?
Required ratio = 475 : 425 = 19 : 17
7. What is the average distance travelled by all the Trucks together ?
Total distance travelled by all trucks = 475 + 350 + 550 + 425 + 525 = 2325 km
Average distance = 2325/5 = 465 km .
8. 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?
Time taken by truck C = 550/55 = 10 hours.
9. The distance travelled by Truck A is approximately what per cent of the total distance travelled by Truck E and C together ?
Required percentage =( 475)/ ( 550 + 525) ] X 100 = 44% ( approx)
10. If the time taken by Truck B to cover the given distance was 8 hours, what was the average speed of the truck ?
Speed of truck B = 350/8 = 43.75 km/hr

- (5) None of these
Required percentage = [( 42.5 – 37.5)/(37.5)]X 100= 13.33 %
4. What is the respective ratio of the number of products not sold by the company in the year 2007 to those not sold in the year 2005 ?
- (1) 3 : 1

The following line graph gives distance (in km) travelled by five different trucks in a day.
6. 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
