Question

Answer 1

Given,

0.8 A=B.,....(1)

B= 0.7 C.....(2)

From 1and 2,we get

0.8 A= 0.7 B

B= 0.8A/0.7

Answer 2

The required percentage is 19.04762%.

Step-by-step explanation:

Consider the provided information.

Let C is 100.

B is 30% less than C.

That means the value of B is 70.

It is given that A is 20% more than B.

Therefore,

$A = 70+\frac{20}{100}\times 70$

$A = 70+14$

$A = 84$

That means the value of A is 84.

Now we need to find by what percent C is greater than A.

$\%=\frac{100-84}{84}\times100\approx19.04762$

Hence, the required percentage is 19.04762%.
