Question

what should be subtracted from 10 12 19 24 to get the nos which are in proportion​

Answer 1

Step-by-step explanation:

Let the number to be subtracted be cx

(10-x):(12-x)::(19-x):(24-x)

(10-x)(24-x)=(19-x)(12-x)

240-10x-24x+x^2 =228-19x-12x+x^2

Now solve

Answer 2

Step-by-step explanation:

SOLUTION :

Let the number Subtract be x

Then ,

$→ (10 - x) : ( 12 - x ) :: ( 19 - x ) : ( 24 - x )$

$→ (10- x)(12 - x ) :: ( 19 - x )( 24 - x )$
