D. 8.0%

View Answer	Favorite Question

Answer: Option B

Total defective parts = 6 + 8 = 14

% of defective parts = {(14/200)×100}% = 7%

View Answer	Favorite Question

Answer: Option B

Explanation:

5 shirt , 5 pairs of trousers and 3 hats = 710 TK - - - - - (i)

Now, multiplying both sides by 2,

10 shirt , 10 pairs of trousers and 6 hats = 1420 TK - - - - - - - (ii)

Again, 11 shirt , 11 pairs of trousers and 8 hats = 1590 TK - - - - - - (iii)

Now, {(iii) - (ii)}>> 1 shirt , 1 pair of trousers and 2 hats = 170 TK - - - - - (iv)

{(iii)×5}>> 5 shirt , 5 pairs of trousers and 10 hats = 850 TK - - - - - - (v)

Now, {(v) - (i)}>> 7 hats = 140 TK

So, 1 hat = 140/7 = 20 TK

From (iv), 1 shirt , 1 pair of trousers and 1 hat = 170 - 20 = 150 TK
