Question

Out of the shirts produced in a factory, 15% are defective, while 20% of the rest are sold in the domestic market. If the remaining 8840 shirts are left for export, then the number of shirts produced in the factory is

• A. 13600
  
• B. 13000
• C. 13400
  
• D. 14000

Answer 1

The correct option is B

13000

Let the number of shirts be 100.
Then defective shirts = 0.15 x 100 = 15
Shirts good to go = 100 – 15 = 85
Shirts sold in domestic market = 0.2 x 85 = 17
Shirts for exports = 85 – 17 = 68
By unitary method:
When shirts for export are 68, total number of shirts is 100.
Hence, total number of shirts produced = $\frac{100}{68}\times 8840$ = 13000.
