Answer:

There are three numbers. Six - seventh of the first number is equal to fourty - three percent of the second number. The second number equal to two-fifth of the third number and the third number is 1500. Find 21% of the first number

Answer 2

21% of first number is 63.21.

Given:

• There are three numbers.
• $\frac{6}{7}^{th} \:$ of the first number is equal to $43\%$ of the second number.
• The second number equal to $\frac{2}{5}^{th}$ of the third number and the third number is 1500.

To find:

• Find 21% of the first number.

Solution:

Step 1:

Calculate the second number.

Let second number be 'x'.

ATQ,

$x = \frac{2}{5} \times 1500$

$x = 2 \times 300$

$\bf x = 600$

Thus,

The second number is 600.

Step 2:

Calculate the first number.

Let the first number be 'y'.

ATQ,

$\frac{6}{7} \: of \: y = 43\% \: of \: 600$

$\frac{6}{7} y = \frac{43}{100} \times 600$

$y = \frac{43}{6} \times 6 \times 7$

$\bf y = 301$

Thus,

First number is 301.

Step 3:

Calculate the 21% of the first number.

$=21\% \: of \: 301$

$= \frac{21}{100} \times 301$

$= 63.21$

Thus,

21% of first number is 63.21.
