In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives. 336 170 748…

In each row, second column element is the difference of the product of the digits of first column element and product of digits of third column element.

1st row:

336 = 3 x 3 x 6 = 54

748 = 7 x 4 x 8 = 224

Now, subtract

224 - 54 = 170.

2nd row:

523 = 5 x 2 x 3 = 30

349 = 3 x 4 x 9 = 108

Now, subtract

108 - 30 = 78.

Similarly,

3rd row:

431 = 4 x 3 x 1 = 12

328 = 3 x 2 x 8 = 48

Now, subtract:

48 - 12 = 36.

Hence, 36 is the correct ans.
