Answer 2

Hope these will help




Let the number of male employees in the firm be p and that of female employees be q.
According to the question,

5200 × p + 4200 × q
= 5000
p + q

⇒ 52p + 42q = 50 (p + q)
⇒ 52p + 42q = 50p + 50q
⇒ 52p – 50p = 50q – 42q
⇒ 2p = 8q
⇒ p = 4q
∴ p + q = 4q + q = 5q
∴ Required percent =
y
× 100 = 20%
