A sells to B goods at five-thirds the rate of profit at which B has decided to sell it to C. C, on other hand sells it to D at one-third the rate of profit at which B sold it to C. If D gives Rs. 2145 to C at 10%, how much did A buy it for ?	Pick one.
A) 1000 B) 1100 C) 1200 D) 1300 E) 1400
let profit rate of b = x   acc to question profit rate of a becomes 5/3 x   and that of c= 1/3 x which is given as 10%   1/3 x= 10   therefore x=30   now b=30% , a=50%   now we will find out c's price-   11/10 * price = 2145   price = 1950   in similar way we will find out b's price as we know that profit is 30%   therefore 130/100 * price = 1950   so b 's price =1500   similarly for a ('profit is 50%)   150/100 * price = 1500   on solving it we get   a's price = 1000   1000NSWER:1000
