Answer»

20 sold at 5% profit: 20 * Rs.40 * 1.05 = Rs.840.

100 sold at 20% profit: 100 * Rs.40 * 1.2 = Rs.4800.

Difference: RS.4800 - Rs.840 = Rs.3960.

80 sold at P profit to make the difference: 80 * Rs.40 * P = Rs.3960.

P = 99/80 = 1.2375.

Gain percentage = P - 100% = 0.2375.

Gain percentage = 23.75%
