   b) 120 millions
   c) 130 millions
   d) 125 millions
   e) None of these
   
   Answer & Explanation

   Answer – a) 90 millions
   Explanation :
   Maharashtra = 500*(22/100)*8/11 = 80 million
   Chhattisgarh = 500*(9/100)*2/9 = 10. So total = 80 + 10 = 90 millions
   
   
   
2. What is the total number of male literate from Rajasthan?
   a) 13 million
   b) 15 million
   c) 16 million
   d) can’t be determined
   e) None of these
   
   Answer & Explanation

   Answer – d) can’t be determined
   Explanation :
   Total population of Rajasthan = 500*10/100 = 50 million. We can calculate the number of women and men. We can calculate the number of literates and illiterates in Rajasthan. But in the number of literates we can’t calculate the number of male literate.
   
   
   
3. In Chhattisgarh 90% of males and 85% of females are literate, what is the total number of illiterates?
   a) 6.66 million
   b) 5.78 million
   c) 7.48 million
   d) 8.38 million
   e) None of these
   
   Answer & Explanation

   Answer – b) 5.78 million
   Explanation :
   Population of Chhattisgarh = (9/100)*500 = 45 million
   total illiterate = 45*(3/7)*(10/100) + 45*(4/7)*(15/100) = 5.78 million (approx)
   
   
   
4. What is the ratio of illiterate of Delhi to literates of Orissa?
