C.P of 1000 pencils = 3000 Rs.
C.P of 1 = 3 Rs.
C.P of 200 = 600 Rs.
Gain = 5%
S.P = C.P*(100+G)/100
= 600*105/100 = 630 Rs.
Overall gain to be made = 15%
C.P = 3000
S.P = 3000*115/100 = 3450 Rs.
C.P of remaining pencils = 2400
S.P of these must be = 3450 - 630 = 2820
Gain = 2820 - 2400 = 420
Gain% = 420/2400 * 100 = 17.5%
Hence the remaining should be sold at 17.5% profit to get an overall gain of 15%.
Hope it helps.
