[jan_sunil]

Today only i attempted this test,
attepted questions - 1,2,4,6,7,9,11,12,13,14,15,17,19,23, got all correct except 13. means 14*4-1 : 55
Hello Aarav, what about official solutions? when shall we expect?

someone please explain answer to q.13 (area one, how this can be 25??)

[Catalyst2008]

can someone explain Q 8...sum of a+root(b) and its reciprocal is an integer...I could not get started with this question..I read some post with conjugate of a+root(b)...but it asks the sum...please explain this one

and Q 10 also...I feel exactly 1 is true i.e. 1st one.
i) satisfies...0 belongs to S,some y does not belong to S, so 0+y will also not belong to S.
ii)If -2 belongs to S, its not necessar that 2 will also belong to S
iii)If 2(x) belong to S, 3(y) belongs to S...not necessary that 5(x+y) will also belong to S.
iv)S must be infinite...not must be!

Relax and wait for the official solutions tomorrow. If you aren't able to crack a problem then it doesn't mean that the KEYS are wrong.

When will be our next test?
