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.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
13 : 34 :: 587 : 1756 :: 575 : ?
Show answer & explanation
Correct answer: A
Explanation
13 : 34 :: 587 : 1756 :: 575 : ?
Just as
13 : 34
13 × 3 − 5 = 39 − 5 = 34
and
587 : 1756
587 × 3 − 5 = 1761 − 5 = 1756
Rule: Second number = (First number × 3) − 5
Similarly
575 : ?
575 × 3 − 5 = 1725 − 5 = 1720
