Four shops—A, B, C, and D—manufacture and sell items of the same kind. Shop A sold twice as many items as it left unsold. The number of items produced in Shop B is 20 more than Shop A, Shop C produced 33.33% less items as number of items produced by A. Number of unsold items in shop B is 25% more than the same in shop A. Number of sold item in shop C is 2/3rd of total unsold items of shop A and B together. Number of unsold items in shop D is double of the number of unsold items in shop C. Shop D produced 12.5% more items than number of items produced in shop C. Number of item produced in shop A is 120.
Out of the total items produced by Shop A, the ratio of gadget items to plastic items is 5:3. If the number of plastic items sold by Shop A is 12, then find the number of unsold gadget items in Shop A.

Shop A produced = 120
Shop A sold = 2× unsold
Let unsold = x ⇒ sold = 2x
So, total = x + 2x = 3x ⇒ 3x = 120 ⇒ x = 40, sold = 80
Shop B:
Produced = A + 20 = 120 + 20 = 140
Unsold in B = 25% more than unsold in A = 40 + 25% of 40 = 40 + 10 = 50
Sold = 140 - 50 = 90
Shop C:
Produced = 33.33% less than A = 120 - (1/3 × 120) = 120 - 40 = 80
Now:
Total unsold in A + B = 40 + 50 = 90
Sold in C = (2/3) × 90 = 60
So, Unsold = 80 - 60 = 20
Shop D:
Unsold = 2 × unsold in C = 2 × 20 = 40
Produced = 12.5% more than produced in C = 80 + 12.5% of 80 = 80 + 10 = 90
Sold = 90 - 40 = 50

Calculation
In shop A, Gadget : Plastic = 5 : 3 in 120 items
Total parts = 5 + 3 = 8
Gadget items = (5/8) × 120 = 75
Plastic items = (3/8) × 120 = 45
Plastic sold = 12 ⇒ Plastic unsold = 45 - 12 = 33
Total unsold in A = 40
⇒ Gadget unsold = 40 - 33 = 7
