Which least number must be subtracted from each of the term 14, 36, 20, 54 to make them proportional?
Answer & explanation
Correct answer: option 1
To make these numbers in proportion, the condition should be:
(14 - a) : (36 - a) :: (20 - a) : (54 - a)
Check from the option, which is the best way to find the number.
So, Option (a):- 3 will justify the equation.
(14 - 3) : (36 - 3) :: (20 - 3) : (54 - 3)
11 : 33 :: 17 : 51
1 : 3 :: 1 : 3
Therefore, 3 is correct answer.
