Answer 2

Given:

When A increases by 18% B increases by 16%, When B increases by 18% then C increases by 9%.

To Find:

If A is increases from 32 to 48, C is increased from 80 to which value?

Solution:

1. It is given that if A is increased by 18% then B increases by 16%,

=> If A increases by 1% then B increases by (16/18)%.

2. It is given that if C is increased by 9% then B increases by 18%,

=> If C increases by 1% then B increases by 2%,

3. If B increases by 1% then, A increases by (18/16)%,

=> If B increases by 2 %, A increases by (9/4)%,

=> If C increases by 1 % then, A is increased by (9/4)%.

4. It is given that A is increased from 32 to 48, The value is increased by 50%,

=> If A is increases by 1% then C is increased by (4/9)%,

=> If A is increased by 50% then C is increased by (200/9)%,

=> The value of C is increased by 22.22%,

=> Final value of C = 80+ 22.22% of 80,

=> Final value of C = 97.77.

Therefore, the value of C increases to 97.77.
