Question

2. In a class of 10 students, 3 failed in History, 6 failed in Geography and 2 failed in both. How many passed in both the subjects ?

1. 1
2. 2
3. 3
4. 0

Answer 1

I think the answer is 3.because 1 failed for history and 4 failed in geography and 2 failed in both.10 - (1+4+2) = 3
Hope it helps and pls mark as the best answer. :-)

Answer 2

This is may be a hypothetical question which i prefers because there are only 10 students and if we calculate among these there will be some mistake in data which u have raised in these blog..?? So i think u must check your data..
