Two persons A and B have unequal number of items with them and they sell at different prices but earn the same sum. If A sells at B's price and B sells at A's price they would earn Rs. 19600 and Rs. 3600 respectively. If A has 44 items more than B, how many total items do they have in all?

hi

a has m items at x price ..while b has n items at y price. from given information we can get 3 equations mx=ny......@1 m-n=44....@2 my=19600 nx=3600......@3 after eq @3 we can get x and y value in terms of m,n ..put it in eq@1 then we will get, 3600(m)/n=19600(n)/m. ...eq@2 also put in .. n=33,-13.2 m=77, positive are real so, n 33 m 77 total items do they have in all=110.
