Question

if 30% of 1520 + 40% of 800 = x% of 5000, find the value of x ? ​

Answer 1

Answer:

30/100 *1520 + 40/100*800= x/100 * 5000

3* 152+ 40*8 = 50x

456+ 320 = 50x

776 = 50x

x = 15.52

I hope it helps..

Answer 2

The value of $x$ is 15.52%.

Step-by-step explanation:

Given:

$30\% \ of\ 1520 + 40\% \ of\ 800 = x\% \ of\ 5000.$

To Find:

The value of $x$ .

Solution:

As given -  $30\% \ of\ 1520 + 40\% \ of\ 800 = x\% \ of\ 5000.$  

$30\% \ of\ 1520 + 40\% \ of\ 800 = x\% \ of\ 5000.$

$\frac{30}{100} \times1520 + \frac{40}{100} \times 800 = \frac{x}{100} \times5000$

$456+320=50x$

$50x=776$

$x=\frac{776}{50}$

$x= 15.52\%$

Thus, the value of $x$ is  15.52%.
