Question

Ifa:b=3:2 and b:c=3:2, let us find the value of (a+b):(b+c)

​

Answer 1

answer = 3/2

Step-by-step explanation:

a/b= 3/2 ,

b/c=3/2 so,

( a+b)/(b+c) = (3+3)/(2+2) = 6/4 = 3/2

Answer 2

Answer:

We are given with two simple ratios

a:b=2:3,

b:c=4:5

When we want the combined ratio of these kind of ratios like a:b:c, we do have a small trick.

In a:b:c the ratio component of ‘a’ will be the product of compnent of ‘a’ in a:b and component of ‘b’ in b:c I.E., 2*4=8. a=8.

Component of ‘b’ will be product ‘b’ components in both the ratios I.E., 4*3=12. b=12

Component of c will be product of Component of b in a:b and c component in b:c I.E., 5*3=15. C=15
