If the total population of the given states is 31,5000, then what was the total number of illiterate people in Goa and M.P.?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 65,520.
the total population of Goa = 12%
hence
⇒ 315000 × 12/100 = 37,800
Goa Literacy ratio = Literate : illiterate = 3 : 2
illiterate people in Goa = 37800 × 2/5 = 15120
the total population of M.P. = 20%
hence
⇒ 315000 × 20/100 = 63000
M.P Literacy ratio = Literate : illiterate = 1 : 4
illiterate people in M.P = 63000 × 4/5 = 50400
the total number of illiterate people in Goa and M.P. = 15120 + 50400 = 65520
