Question

The amount of $In each The amount of $ Total

Answer 1

Let Lydia invest $x

Half of her stock pays 11% dividend.

So mathematically the amount will be

$\frac{x}{2}\times\frac{11}{100}=\frac{11x}{200}$

With the other half, she pays stocks in 14% interest

So mathematically

$\frac{x}{2}\times\frac{14}{100}=\frac{14x}{200}$

Her total annual interest is $420

So

$\frac{11x}{200}+\frac{14x}{200}=420\Rightarrow25x=84000\Rightarrow x=3360$

She invested $3360 in total

And $1680 in each.
