Answer 1

Question -:

Find the number whose 30% is 342.

Answer -:

• The required number is 1140.

Step-by-step explanation -:

Let the number be x.

Given -:

$30\% \: of \: x \: = 342$

$\frac{30}{100} \times x = 342$

$\frac{3x}{10} = 342$

$3x = 342 \times 10$

$3x = 3420$

$x = \frac{3420}{3}$

$x = 1140.$

So, 30% of 1140 is 342.

How to verify?

To verify your answer, just find out 30% of 1140 and see if you get 342 or not.

$30\% \: of \: 1140$

$\frac{30}{100} \times 1140$

Simply reduce the numbers, first cut off all the zeroes. We are left with -:

$\frac{ 3 }{1} \times 114$

$\frac{3}{1} = 3$

So, we have -:

$3 \times 114 = 342.$

Since 30% of 1140 is 342,

Hence verified ✔️✔️
