Quantitative Reasoning – Practice – Can you find out this 4-digit number!




From statement 3, W must be greater than 4 (for Z to be a digit). Possible values of W= 5,6,7,8,9.  ——-(M)

From the above & statement 2, Y could be 4,5,6,7,8 (for W to be a digit)  ————(N)

Now, from statement 1, X= W + Y + Z

Now from  statement M & N, possible sum of W and Y are (9,10,11….17). Given the conditions of the questions, W+Y must be 9 where W=5 and Y=4.

Z must be 0 to make sure X is a digit.


Four digit integer=5940.
