Question

Three numbers A;B and C are in the ratio of 12:15:25 if sum of these numbers is 312 and the ratio between the difference of B and A and the difference of C and A

Answer 1

Answer:

3/13

Step-by-step explanation:

A=12x

B=15x

C=25x

according to question

12x+15x+25x=312

52x=312

x=6

therefore

A=126=72

B=156=90

C=256=150

B-A=

90-72=18

C-A=

150-72=78

ratio between B-A and C-A

=18/78

=3/13
