Answer:
C.P of 1000 pencils=Rs.3000
C.P of one pencil= 3000/1000 =Rs.3
Manish sold 200 pencils at the gain of 5%
C.P of 200 pencils= 3(200) =Rs.600
Profit= 5% of CP of 200 pencils= 5*600/100 = Rs.30
S.P of 200 pencils= C.P of 200 pencils + Profit = 600+30 =Rs.630
Manish wants to make a profit of 15% of whole transaction
Profit of whole transaction= 15*3000/100 =Rs.45
Profit to be made for 2nd transaction
= Profit of whole transaction - Profit of 1st transaction
= 450-30
= Rs.420
C.P of remaining pencils= 800*3 =Rs.2400
Let 'x' be the profit percentage of 2nd transaction
Profit of 2nd transaction= C.P of remaining pencils * (x/100)
=> 420 = 2400x/100
=> 420 = 24x
=> x = 420/24
=> x = 17.5
Answer is 17.5
some idiot is reporting my answer . My answer is correct

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.
