Select the option that is related to the fourth number in the same way as the first number is related to the second number and the fifth number is related to the sixth number.
32 : 99 :: ? : 45 :: 16 : 51
32 : 99
32 ==>Â $$32\times3+3$$ = 96+3 = 99
16 : 51
16Â ==> $$16\times3+3$$ = 48+3 = 51
? : 45
? ==> $$? \times3+3$$ =45
$$? \times3 =Â 45-3$$
$$? \times3 = 42$$
? = 14
Hence 14 will come in place of the question mark.
