Question

Which number should be subtracted from 13,25,and 55 so that the resulting numbers are in continued proportion​

Answer 1

Answer:

13. => 12, 11, .10, .9, .. 8, .. 7, . 6, . 5, . 4, . 3, . 2, . 1

25. .=> 24, 23, 22, 21, 20, .19, .18, .17, .16, 15, 14, 13

55. => 54, 53, 52, 51, 50, 49, 48, 47, .46, 45, 44, 43

Answer.

13 - 10 ==> . 3

25 - 10 ==> 15

55 - 10 ==> 45

If (13, 25, 55) are all reduced by ( 10 ) the result is.

.= ( 3, 15, 45 ).

The proportional increase each time is ( 3 ).
