The population of a district is 360000, out of which 225000 are males. 35% of the population is literate. If 17% males are literate, then what percentage of females are literate?

A68%

B67%

C63%

D65%

Answer:

D. 65%

Read Explanation:

Total population = 360000
Males = 225000 ⇒ Females = 360000 − 225000 = 135000

Total literate people

35% of 360000
=0.35×360000=126000= 0.35 \times 360000 = 126000
Literate males

17% of 225000
=0.17×225000=38250= 0.17 \times 225000 = 38250
Literate females

126000−38250=87750126000 - 38250 = 87750
Percentage of literate females

87750135000×100=65%\frac{87750}{135000} \times 100 = 65\%
