Which least number must be subtracted from each of the term 35, 50, 25, 35 to make them proportional?
Answer & explanation
Correct answer: option 3
To make these numbers in proportion, the condition should be:
(35 - a) : (50 - a) :: (25 - a) : (35 - a)
Check from the option, which is the best way to find the number.
So, Option (c):- 5 will justify the equation.
(35 - 5) : (50 - 5) :: (25 - 5) : (35 - 5)
30 : 45 :: 20 : 30
2 : 3 :: 2 : 3
Therefore, 5 is correct answer.
