Calculate the ratio of people who like only RNBDJ to the number who like only Ghajni.

• A. 1: 3
• B. 1: 2
• C. 2: 3
• D. 4: 5
• E. 1: 4

Answer 1

The correct option is C 2: 3

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
160: 240 = 2: 3. Hence option (c)
