Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number.
15 : 125 :: 27 : ? :: 36: 1728
Answer & explanation
Correct answer: option 4
15 : 125 :: 27 : ? :: 36: 1728
The logic followed here is ⇒ (1st no. ÷ 3 )3 = 2nd no.
Here,
15 : 125
⇒ (15 ÷ 3)3 = 53 = 125
and
36 : 1728
⇒ (36 ÷ 3 )3 = 123 = 1728
Hence
27 : ?
⇒ (27 ÷ 3)3 = 93 = 729
