There are two rows of numbers in each question. The upper row is complete and in the lower row one number is missing. Find a suitable number to fill the blank space so that the symmetry with the upper row is maintained.
The table can be read row-wise. The first number when multiplied with the half of the third number, gives the second number, i.e.
17*(12/2)= 17*6= 102
Similarly for the second row, 15*(10/2)= 15*5= 75 - Option B
