Hi ayush030394

It will be great for the users / learners if you could present your thought process. OA is already provided, so we need few discussions :-)

Consider three real numbers, x, y, and z. Is z the smallest of these numbers?

A. x is greater than at least one of y and z

B. y is greater than at least one of x and z

Statement 1: x is greater than at least one of y and z
So, x> y or x >z but it is not clear y>z or z>y, -> Insufficient.

Statement 2: y is greater than at least one of x and z.
So y>x or y>z but it is not clear x>z or z>x. -> insufficient.

1+2 we can consider x>z and y>z -> Sufficient.

Answer: C

If I am wrong kindly correct me.

OE

Statement A: implies \(x>y\) or \(x>z\) or \(x>y\) and \(z\). Hence Insufficient

Statement B: implies \(y>x\) or \(y>z\) or \(y>x\) and \(z\). Hence Insufficient

Combining both statements, we can get \(y>x >z\) or \(x>y>z\). In either case \(z\) is the smallest.

Option C
