The correct option is
C ratio of earning that are disturbed through dividend
Payout ratio = Dividend/ Total earnings available for shareholders
For example let the dividend declared be Rs.100000 and the total earnings for the shareholders be Rs.500000 therefore,
Payout ratio = 100000/500000
= 0.2 times
So dividend declared would be 0.2 times the earning made and the remaining 0.8 times of the earnings would be retained by the company in the form of reserves and surplus.
