Answer 1

Answer:

here is your answer

Step-by-step explanation:

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.
