Select the option that is related to the fifth number in the same way as the second number is related to the first number and fourth number is related to third number.
6 : 12 :: 15 : 75 :: 18 : ?
Answer & explanation
Correct answer: option 3
6 : 12 :: 15 : 75 :: 18 : ?
The logic followed here is :
IST NUMBER × (IST NUMBER ÷ 3) = IIND NUMBER
AS
IST NUMBER × (IST NUMBER ÷ 3) = IIND NUMBER
= 6 × (6 ÷ 3)
= 6 × 2
= 12
AND
15 × (15 ÷ 3) = IIND NUMBER
= 15 × (15 ÷ 3)
= 15 × 5
= 75
SIMILARLY
18 × (18 ÷ 3) = IIND NUMBER
= 18 × (18 ÷ 3)
= 18 × 6
= 108
