3x - 13 = (6, 7, 8 or 9) any of these
Let the number be 8
3 × 8 - 13 = 11
Hence, The Number should be less than 8
Let the number be 6
3 × 6 - 13 = 5
Hence, The Number should be greater than 6 so, that the resultant should be from the options
Now, Take x = 7
3 × 7 - 13 = 21 - 13 = 8
Hence, The Result is 8
Additional Information
It only seems that the information is incomplete, but if you check the solution, you will understand the logic. This is BPSC/BSEB previous year question and is correct.
Here, the value will have to be greater than 6, since using 6, we do not get any of the 4 options.
Also, if we take 8, the answer is more than all the given options,
Now when we take x = 7, the answer matches and hence 3 × 7 - 13 = 21 - 13 = 8 is the correct option
