we have condition is {4 terms } + {5 terms } + {6 terms } + {7 terms } + ...... < 200terms so, 4 + 5 + 6 + 7 + ..... n < 200 (1 + 2 + 3 )+ 4 + 5 + 6 + 7 + .... n < 200 + 1 + 2 + 3 n(n + 1)/2 < 200 + 6 = 206 n(n + 1) < 412 it is possible when n ? 19 [ because n is integers so I assume only integers value of n that\'s why n ? 19] so, n = 19 so, Sn = 4 + 5 + 6 + 7 + ... + 19 Sn = 19(19 + 1)/2 - (1 + 2 + 3) = 184 hence, after 184 terms , sequence has 20 terms .e.g., 12344444444444444444 hence, 200th term is not other than 4 hence, 4 is in 200th position.

Since, At the end of 100th day for the first commodity, the price is C1=100+0.1*100 = 110, after 100th day price remains same. For 2nd commodity, At the end of 100th day, C2=89+0.15*100 = 104 (for every 10 days, C2 get increased by 1.5 (i.e 10*0.15) So,) at 110th day, C2=104+1.5 =105.5 at 120th day, C2=105.5+1.5 =107 at 130th day, C2=107+1.5 =108.5 at 140th day, C2=108.5+1.5 =110 So, C1 and C2 are equal at 140th day. 140th day in 2007 is May-20
