Question

The number of illiterate people in the country decreased from 150 lakhs to 100 lakhs. What is the decrease% ?

Answer 1

Given that number of illiterate persons in a country decreased from 150 lakhs to 100 lakhs in 10 years so percentage of decrease :

= (total depriciation / total initial population) * 100

= (final population - initial population)/ intial population * 100

= ((150 - 100)/150) *100

= (50/150) * 100

= 100/3
= 33.33

So percentage of decrease = 33.33 percent(answer)
