If the question can be answered with the help of statement I alone,
If the question can be answered with the help of statement II alone,
If both,statement I and statement II are needed to answer the question
If the question cannot be answered even with the help of both the statements.
If the data in either statement I or statement II alone is sufficient to answer the
question

1 Answer

Answer :

Let the current ages of X and Y be a and b respectively
From the question:
A=3(a-b)
From statement I:
A=b + 17
B = a-17
Therefore, a = 3(a-17-3)
a=3a-60
2a=60
A=30
Hence, X is 30 years old
From statement II:
a + 9 = 3b
b=(a+9)/3
Substituting this in first equation,
A=a+9-9
Hence, no result
Therefore, statement I alone is sufficient
Answer :a

Last Answer : Answer: B) Let X be the event of the group X pass Let Y be the event of the group Y pass Then, X'= Event of the group X's fail and Y'= event of the group Y's fail. Therefore, p(X) = 3/5 and p(Y) = 5/7, P(X') = 1 - P( ... )] + p[(Y And X')] = p(X) * p(Y') + P(Y) *P(X') = (6/35 + 10/35) = 16/35
