Question

# Given that a:b::c:d, then which of the following follows Componendo and Dividendo property? d(a−b)=b(c−d) (a−b):b=(c−d):d a−ba+b=c−dc+d Both a and b

Solution

## The correct options are C a−ba+b=c−dc+d When a, b, c, and d are in proportion i.e. when a : b :: c : d, then ab=cd Applying componendo and dividendo, a−ba+b=c−dc+d
