Let number of males = m
Since total 'p' persons, number of females = p - m
Now, x% of p = p*x/100
Number of males who can read and write = y% of m = m*y/100
Number of females who can read and write = z% of (p-m) = (p-m)*z/100
Total number who can read and write = Number of males who can read and write + Number of females who can read and write
px/100 = my/100 + (p-m)Z/100
Solving for m: m = p(x-z)/(y-z)
