Question

9. The number of illiterate persons in a country decreased from 250 lakhs to 150 lakhs in 10 years. What is the percentage of decrease?​

Answer 1

Answer:

40 percent

Step-by-step explanation:

no of persons decreased = 250 - 150 lakhs

                                          =  100 lakhs

percentage of decrease = no of persons decresed ÷ total number of persons

                                         = 100 ÷ 250

                                          = 0.4

percentage = 0.4 × 100

                    = 40%
