Question

What should be subtracted from 8, 15, 23 and 51 so that the resulting numbers are in
Proportion. ?​

Answer 1

Answer:

ans is 3 3 should be subtracted from the no. so that resulting is continuing proportional

Step-by-step explanation:

let the no be X

8-x/15-x=23-x/51-x

(8-x).(51-x)=(15-x)(23-x)

8x51-8x-51x+x²=15x23-15x-23x+x²=0

408-345-8x-51x+15x+23x+x²-x²=0

63-21x=0

-21x=-63

X=63/21

X=3

note continued pro proportion means a/b=b/c

i.e AC=b²

u can check that no 8-3,15-3,23-3,51-3

i.e 5,12,20,48 Are in continued proportion.
