Answer:C Explanation:Number of males in U.P = [3/5 of(15% of N)] = 3/5 X 5/100 X = 9X N/100 where N = 3276000. Number of males in M.P = [3/4 of(20% of N)] = 3/4 X 20/100 X = 15X N/100 Number of males in Goa = [3/8 of(12% of N)] = 3/8 X 12/100 X = 4.5X N/100 Therefore Total number of males in these three states = (9 + 15 + 4.5) xN/100 =(28.5 X N/100) Therefore Required Percentage = [((28.5 X 8/100)/N) X100]% =28.5%

Answer:D Explanation:No. of illiterate people in A.P. = [7/9 of(25% of 3276000)]=637000 No. of illiterate people in M.P. = [4/5 of(20% of 3276000)]=524160 Therefore Total number = (637000 + 524160) = 1161160.

If in the year 1998, there was an increase of 10% in the population of U.P. and 12% in the population of M.P. compared to the previous year, then what was the ratio of populations of U.P. and M.P. in 1997?

Answer:A Explanation:Let x be the population of U.P. in 1997. Then, Population of U.P. in 1998 = 110% of x =(110/100) X x Also, let y be the population of M.P. in 1997. Then, Population of M.P. in 1998 = 112% of y = (112/100) X y Ratio of populations of U.P. and M.P. in 1998 = [(110/100 )X( x)/(112/100) X (y) = 110x/112y From the pie-chart, this ratio is 15/20 Therefore, 110x/112y = 15/20 =x/y x/y= (15/20) X (112/110) = 42/55 Thus, ratio of populations of U.P. and M.P. in 1997 = x : y = 42 : 55.
