Select the option that is related to the third number in
the same way as the second number is related to first number and the sixth number is related to the fifth number. 45 : 36:: 68 : ? :: 54 : 45Solution
The product of first and second digits of the first number is added to the square of the first digit of the first number to obtain the second number. 45 → [(4 × 5) + (4)² ] = [20 + 16] = 36 54 → [(5 × 4) + (5)² ] = [20 + 25] = 45 68 → [(6 × 8) + (6)² ] = [48 + 36] = 84.
