What is the value of x ?

(1) x +1 = 2 - 3x
(2) 1/(2x) = 2

Sol: We need to find value of x
From St 1, we have x+1=2-3x or 4x= 1 ---->x=1/4.....So B,C and E ruled out
From St 2, 1/(2x)=2 ------> x =1/4.

Ans D

What is the value of x ?

(1) x +1 = 2 - 3x
(2) 1/(2x) = 2

Statement I is sufficient:

x + 1 = 2 - 3x

4x = 1

x = 1/4

Statement II is sufficient:

1/(2x) = 2
x = 1/4

Answer is D (Both the answer options are giving the same answer as well)

Yes answer is D

As both statements are sufficient
(1) x +1 = 2 - 3x
x = 1/4

(2)1/(2x) = 2
x = 1/4
