Which least number must be subtracted from each of the term 17, 31, 24, 45 to make them proportional?
Answer & explanation
Correct answer: option 4
To make these numbers in proportion, the condition should be:
(17 - a) : (31 - a) :: (24 - a) : (45 - a)
Check from the option, which is the best way to find the number.
So, Option (d):- 3 will justify the equation.
(17 - 3) : (31 - 3) :: (24 - 3) : (45 - 3)
14 : 28 :: 21 : 42
1 : 2 :: 1 : 2
Therefore, 3 is correct answer.
