A) 3000
B) 3500
C) 4000
D) 5000
Correct Answer: D
Solution :
Let the total number of candidates = x |
\[\therefore \]Number of candidates passed in English = 0.6x |
Number of candidates passed in Maths = 0.7x |
Number of candidates failed in both subjects |
= 0.2x |
Number of candidates passed in atleast one subject |
\[=x-0.2x=0.8x\] |
\[\therefore \]\[0.6x+0.7x-2500=0.8x\]\[\Rightarrow \]\[1.3x-0.8x=2500\] |
\[\Rightarrow \]\[0.5x=2500\]\[\Rightarrow \]\[x=\frac{2500}{0.5}=5000\] |
