Question

IF a% of b is c,what will be c% of a?

Answer 1

Answer:

c²/b

Step-by-step explanation:

ab = 100c

ca/100 = c( c)/b = c²/b

Answer 2

If a % of b is c then c % of a is $\frac{c^2}{b}$

Solution:

Given that  

a% of b = c

a% of b can be written as $\frac{a}{100} \times b$

$\frac{a}{100} \times b=c$

$\mathrm{a}=\frac{c \times 100}{b}$  ---- eqn 1

We have to find out what will be c % of a

Let c% of "a" be x

c % of x can be written as $\frac{c}{100} \times x$

$\frac{c}{100} \times a=x$

Substituting the value of "a" from equation 1

$\begin{array}{l}{\frac{c}{100} \times \frac{c \times 100}{b}=x} \\\\ {\frac{c^{2}}{b}=x}\end{array}$

Thus c% of a will be $\frac{c^2}{b}$
