Two glass bulbs A and B are connected by very small tube having a stop cock. Bulb A has a volume of 100 ml and contained a gas while bulb B is empty and has a volume of 150 ml. On opening the stop cock, the pressure of the gas in bulb A will fall down to : 

A

80%

B

60%

C

0.4

D

20%

Total moles initially and finally is constant
`:. 100 xx p^@ + O = 100 xx P + 150 xx P`
`implies P (100 xx P^@)/(250) = 40%` of `P^@.`
