Determine the number of people who like RNBDJ and Singh is King but not Ghajni.

• A. 120
• B. 200
• C. 180
• D. 240
• E. 280

Answer 1

The correct option is D 240

Number of people , who likes at least one movie = 2000 - 120 = 1880

x + 40 + x - 120 + x - 200 + 640 - x + 560 - x + 600 - x + x = 1880
x = 360
The number of people who like RNBDJ and Singh is King but not Ghajni = (600 - 360) = 240. Hence option (d)
