Question

which no should be substacted from 12 ,16 and 21 so that the resultant no would be in continued proportion​

Answer 1

Answer:

Let the number x be subtracted from 12, 16 and 21 so that resultant numbers are in continued proportion. ∴ (12 − x), (16 − x), (21 − x) are in continued proportion. Thus, the number −4 must be subtracted from 12, 16 and 21 so that resultant numbers are in continued proportion.
