1.  If 50 is subtracted from two-third of a number, the result is equal to sum of 40 and one-fourth of that number. What is the number ?
A. 174
B. 216
C. 246
D. 336

Answer: Option B

Explanation:

Let the number be X.

Then, 2X  - 50 = 1X  + 40
           3               4

<=> 2X  - 1X = 90
         3      4
<=> 5X  = 90
       12
<=> X =  90 x 12 = 216
                   5
