As per the details provided in the question.

In the above question, we have the details as follow.

The given data is that decrease in the number of illiterate people is 150 lakh to 100 lakh.

Year 10year.

We have to find the percentage of decrease.

Here we have to use a percentage of decrement.

$\text { Decrease in \% }=\frac{\text { original count }-\text { new count }}{\text { original count }} \times 100$

Substitute the given value in the above equation we get,

$=\frac{150-100}{150} \times 100\\=\frac{50}{150} \times 100\\=\frac{100}{3}\\=33.3 \%$
