Question
The average mark obtained by 130 candidates in a certain
examination is 40. If the average marks of passed candidates are 45 and that of the failed candidates is 20, then what is the number of candidates who passed in the examination?Solution
According to question, => 45 × x + 20 × (130 − x) = 130 × 40 => 45x + 2600 – 20x = 5200 => x = 104
If the expressions G < L ≤ J > B, J ≤ A and G > H are true, which of the following conclusions will be definitely false?
Statements: D ≤ R < E = F, W = B > A ≥ F
Conclusions:
I. E = W
II. D < B
Statement:
Q < B ≥ M; M > T = V; S < J = K ≥ L; V > K
Conclusion:
I. B > S
