Question

If 30% of a number is 12.6, find the number?

Answer 1

Answer:

42

Explanation:

Let the number be =  y

Concluding, y% = y/100

Thus, 30% of a number is equal to 12.6

Representing individual terms in the form of a mathematical expressions ,

30% = 30/100  Of = y

Number =  y

Combining all, the mathematical equations, we get -

= (30/100) x y = 12.6  

= 0.3y = 12.6

y = 12.6/0.3

y = 42 or

Let the no. be = x

In simple terms -

30 % of x = 12.6

30/100 × x= 12.6

x= (12.6 ×100)/30

x = 42

Thus, the number is 42

Answer 2

Answer:

The number is 42.

Explanation:

Given that a number is 30% of a number is given by 12.6.

We have to find that number.

Let us assume the number to be as x.

From the above given statement we have 30% of x is 12.6.

That is $\frac{30}{100} \times x=12.6$

Now we have to find the value for x

So,

$X=\frac{12.6 \times 100}{30}$

After simplification of the above expression, we get the value of x to be as

X=42

Hence the number is 42.
