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)
