She can solve 75 questions per hour.

<u>Solution:</u>

Given that, a lady can solve 100 math problems every 4/3 hours.  

We have to find how many math problems does she can solve per hour?

Now, according to the given information.

In \frac{4}{3} hours ⇒ 100 problems

Then, 1 hour ⇒ "n" problems

So, by chris cross method.

\frac{4}{3} \times n = 1 \times 100

\frac{4}{3}n = 100

n = \frac{3}{4} \times 100\\\\n = 3 \times 25 = 75

Hence, she can solve 75 questions per hour.
