Question

) Find the whole quantity if 70% of it is ₨ 35.​

Answer 1

Answer:

whole quantity is 50

Step-by-step explanation:

According to the information provided in the question it is given as

70% of x is 35

We need to find the whole quantity

As seen in the question it is percentage based question

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%

$\frac{70}{100}\times x =35$

Converting to lowest term  we get

$=\frac{7}{10}$

(As both are divisible by 10)

$0.7x=35\\x=\frac{35}{0.7} \\x= 50$

So the whole quantity is 50

Answer 2

$\huge\rm{ \red{Answer}}$

Let the required quantity be 'x'.

Moreover, 70% refers to 70 out of 100 = 70/100. The expression '×' in algebra is denoted by 'of' , thus

Then, as per the question given

$\sf\dfrac{70}{100} \times x = 35$

$\sf \dfrac{7 \cancel{0}}{10 \cancel{0}} \red x = 35$

$\sf \red{x} = \cancel \dfrac{350}{7} = \red{50}$

Therefore, the required quantity is 50.
