On the basis of given table in question ,
Difference in production of toys of type B and C :
Year 2002 ⇒ 150 – 78 = 72 thousand
Year 2003 ⇒ 180 – 100 = 80 thousand
Year 2004 ⇒ 175 – 92 = 83 thousand
Year 2005 ⇒ 160 – 120 = 40 thousand
Year 2006 ⇒ 185 – 130 = 55 thousand
Total difference in production of toys of type B and C = 72 + 80 + 83 + 40 + 55 = 330 thousands
Number of types of toys = 5Correct Option: B

On the basis of given table in question ,
Let total number of film watchers be 100% .
In city A , If 60% of them watched less than two movies a week , then 40% watched two or more movie per week .
∴ 40% ≈ 2400⇒ 1% = 2400 40 Now , 100% = 100 × 2400 = 6000 40
Similarly for city B,⇒ 100% = 100 × 3000 = 3750 80
For city C,⇒ 100% = 100 × 2400 = 16000 15
Correct Option: D

For city D,⇒ 100% = 100 × 2700 = 6000 45
For city E,⇒ 100% = 100 × 8000 = 32000 25
Hence , A and D cities have the same number of movie watchers , which is 6000 .
