Given : Statements:

I. The total age of P and Q is more than that of R

II. The total age of p and S together is less than that of R.

To Find :  Who is the Youngest among them?

Choose correct option :

a. Statement I alone is sufficient

b. Statement II alone is sufficient

c. Both Statement put together are sufficient

d. Both Statement even put together are not sufficient

Solution:

The total age of P and Q is more than that of R

P + Q > R

P and A can be younger than R , Equal to R or more than R  for examples

P           Q            R

4           5             6

4           6            6

5           4            6

7           8            6

6           6            6

Nothing much can be concluded from this

The total age of p and S together is less than that of R.

P + S   < R

=> P < R , S < R

Hence  P and S are younger than  R

P     Q      R       S

2      6      7       4          P is younger

4      6      7       2          S is younger

Hence Both Statement even put together are not sufficient

correct option is d)
