Answer 1

Answer:

B. 8000

the candidates failed in both subject = 22% the candidates passed in at least one subjects = 100 - 22 = 78% candidates passed in geography = 78 - 72 = 6 candidates passed in history = 78 - 48 = 30 candidates passed in both subject = 100 - ( 6 + 30 + 22) = 100 - 58 = 42 we have candidates passed in both subjects as 3360 ⇒ 42% = 3360 100% = 3360 × 100/42 = 8000
