Let the two digit number be ab
10a+b = 4(a+b)
6a = 3b
2a = b
Possible values of (b,a) include 2,1), (4,2), (6,3) & (8,4)

(1) tens digit is 1
a = 1 => b =2
number is 12

(2) units value is a prime number.
from the possible values, only b=2 satisfies.
so a=1
number is 12.

Either of the options is sufficient. Option D

Hence sufficient. S2 - n=3q+odd integer, where q is any integer i.e. remainder can be 1 which is only odd remainder. any number when divided by 3 and leaving remainder 1 can have remainder 0 or 1 when divided by 2, hence not sufficient. Hence answer A. If u liked my post, please press kudos! _________________ Please give kudos, if you like my post When the going gets tough, the tough gets going...

FROM STATEMENT - I ( Insufficient)

$$3^{x + y} = 3^4$$

Or, $$x + y = 4$$

FROM STATEMENT - II ( Insufficient)

$$3^{x + 2y} = 3^3$$

Or,$$x + 2y = 3$$

FROM STATEMENT - I & II ( Sufficient)

$$x + y = 4$$ or $$2x + 2y = 8$$
$$x + 2y = 3$$

Now, $$x + 2y = 3$$

Or, $$2y = 3 - x$$

Or, 8 - 2x = 3 - x

Or, x = 5 So y = -1

Thus BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked, answer will be (C)
