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

Direction: A survey of movie going habits of city dwellers from 5 cities A, B, C, D and E is given below. The first column gives the percentage of viewers in each city who watch less than two movies a week. The second column gives the total number of viewers who view two or more movies per week. Study the table and answer the questions.

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 .
