If 30 % of 1520 + 40 % of 800 = x % of 5000, find the value of x.

We are given:

• 30% of 1520

$= \frac{30}{100} \times 1520 = 456$$

• 40% of 800

$= \frac{40}{100} \times 800 = 320$$

Total:

$456 + 320 = 776$$

Let the required percentage be $x$.

$x\% \text{ of } 5000 = 776$

$\frac{x}{100} \times 5000 = 776$

$50x = 776$

$x = \frac{776}{50} = 15.52$
