Select the option that is related to the fifth number in the same way as the first number is related to the second number and the third number is related to the fourth number.
33 : 121 :: 27 : 81 :: 45 : ?
Answer & explanation
Correct answer: option 4
33 : 121 :: 27 : 81 :: 45 : ?
The logic followed here is :
( IST NUMBER ÷ 3 )2 = IIND NUMBER
AS
( 33 ÷ 3 )2 = IIND NUMBER
112 = 121
AND
( 27 ÷ 3 )2 = IIND NUMBER
92 = 81
SIMILARLY
( 45 ÷ 3 )2 = IIND NUMBER
152 = 225
