when we blow air in balloon  pressure of balloon increases and volume also increases does not this violates boyle's law ?

Boyle's law :

PV = constant

PV = nRT

Hence n (no. of moles), R and T should be constant to obey Boyle's law.

But while blowing the balloon the no. of moles of gas is not constant 

Hence it does not violet the Boyle's law.
