Cost of 1 dozen(12 eggs) = Rs. 18

Cost of 300(25 dozen) eggs = Rs. 18 *25 = Rs.450

Total gain to be required = 30%

S.P of 300 eggs = C.P*(100+G)/100 = 450*130/100 = Rs.585

He sold 150 eggs at 20% gain

C.P of 150 eggs = Rs.225

S.P = C.P*(100+P)/100 = 225*120/100 = Rs.270

S.P of remaining eggs(to be sold) = 585 - 270 = Rs.315

C.P = Rs.225

Gain = Rs.90

Gain% = G/C.P * 100 = 90/225 * 100 = 40%

Hence, remaining eggs should be sold at a gain of 40%.

Hope it helps.
