The cost price of an article is Rs. 100. To gain 50% after allowing a 50% discount, the market price of the article is:
Rs. 200
Rs. 400
Rs. 350
Rs. 300
Explanation:
S.P.= (100+Gain%) $\times$ C.P./100.
SP= (100+50) $\times$ 100/100
SP = 150
Now,
=>SP = (100-discount%) $\times$ M.P./100
=> 150= (100-50) $\times$ M.P./100
=> 150=M.P./2
=> M.P.=300.
