Given is the % of illiterates So % of literates will be
F
M
2001
40%
50%
2011
60%
60%
And population distribution is
F
M
2001
40%
60%
2011
50%
50%
Let total population in both the years as T So total literate in 2001 will be 0.4×0.4+0.5×0.6=0.46T And total literate in 2011 will be 0.5×0.6+0.5×0.6=0.6T ∴ Increase =0.6T−0.46T=0.14T ∴% increase =
