1.  Questions : How much money do Vivek and Suman have together ?
Statements :

I.  Suman has 20 rupees less than what Tarun has .
II. Vivek has 30 rupees more than what Tarun has .

A. I alone is sufficient while II alone is not sufficient.
B. II alone is sufficient while I alone is not sufficient.
C. Either I or II is sufficient.
D. Neither I nor II is sufficient.
E. Both I and II are sufficient.

Answer: Option D

Explanation:

From I, we have : S = T - 20.

From II, we have : V = T + 30.

Thus, from both I and II, we have : V + S = ( T + 30 ) + ( T - 20 ) = ( 2 T + 10 ).

So, to get the required amount, we need to know the amount that Tarun has.
