What is the difference between the number of cars of model A sold in all the cities together and the number of cars of model E sold in all the cities together?

Correct Answer: (4) 8500
Solution:

Number of cars of model A sold in all the cities together
= (45 + 40 + 64 + 32 + 8 + 21 + 55 + 42 + 29) × 100 = 33600
Number of cars of model E sold in all the cities together
= (20 + 24 + 42 + 12 + 14 + 84 + 48 + 87 + 90) × 100 = 42100
Required difference
= (421 – 336) × 100 = 8500

12. Study the above information carefully and answer the questions.

The number of WX cars of models C and D together sold in the city Delhi is equal to the number of SX cars of which two models together sold in the city Kolkata?

Correct Answer: (5) C and B
Solution:

The number of WX cars of the models A and D together sold in the city Delhi
= 4100 + 8500 = 12600
Number of SX cars of the models B and C together sold in the city Kolkata
= 5400 + 7200 = 12600

13. Study the above information carefully and answer the questions.

What is the difference between the number of BX cars of models B, C and E together sold in Mumbai and the number of WX cars of models A and D together sold in Kolkata?

Correct Answer: (4) 500

16. The following line diagram shows the details about calories per day required for different ages of babies in the first six years after birth. Consider the following graph and answer the questions given below :

What is the difference between total calories consumed by a 2 year old baby in the month of December and that by a 3 year old baby in the month of July?

Correct Answer: (3) 3100
Solution:

Calories per day required
for a 2 year old baby = 1000
Total number of days in December = 31
Total calories consumed in the
whole month = 1000 × 31
= 31000
Calories per day required for a
3- year old baby = 1100
In July, total number of days
= 31
Total calories consumed in the
whole month = 1100 × 31
= 34100
Required difference
= 34100 - 31000 = 3100

17. Study the above information carefully and answer the questions.
