Official Solution:


We’ll go for ALTERNATIVE because there are only a few possible options.

We’ll write down the possible options: 31, 62, 93. Statement (1) eliminates 62, but both 31 and 93 are possible – which one? (A) and (D) are eliminated. Statement (2) eliminates 31, but both 62 and 93 are possible – which one? (B) is eliminated. Combined – only 93 is possible. (E) is eliminated.


Answer: C

Hi Bunuel ,

Is " tens digit three times greater than the units digit" is same as " tens digit is three times units digit" ?

I assumed tens digit here to be > than 3 * units ==> lets says XY is the number ==> X = 3Y+Y . Please correct me
