Note – Number of items manufactured = items sold + items unsold
Total items = total number of shirts and trousers.

Ques : Find the average number of unsold items in shop A and in shop C.

Correct Answer: (a) 80  
Solution:

For shop A:
Total items manufactured = 330
Total items sold = 100 + 150 = 250
Unsold items = 330 − 250 = 80

Similarly,

Required average = (80 + 80) / 2 = 80

8. If the 62% of the items manufactured by C are shirts, then the unsold trousers in C is what percentage of total unsold items in shop D?

Correct Answer: (d) 51  
Solution:

Total shirts manufactured = 62% of 450 = 279
Total unsold shirts = 279 − 250 = 29
Total unsold trousers = 80 − 29 = 51
Required average = 51/100 × 100 = 51%

9. Find the ratio of shirts sold by A and C together to twice the total unsold items in D.

Correct Answer: (e) 7:4
Solution:

Required ratio = 100 + 250 : 2 × 100 = 350 : 200 = 7 : 4

10. Find the difference between total sold items and total unsold items in all the shops.
