    A)  35%                

    B)  37.5%

    C)  40%                

    D)  30.5%

    Correct Answer: B

    Solution :

    [b] Let us consider a packet or rice marked 1kg. It's actual weight is 80% of 1000 gm = 800 gm Let C. P. of each gm be Rs. 1 Then, C.P. of this packet = Rs. 800 S.P. of this packet= 110% of C.P. of 1kg \[=\frac{110}{100}\times 1000=Rs.\,\,1110\] \[\therefore \,\,\,Gain\,%=\frac{(1100-\,800)}{1100}\times 100=37.5%\]
