Solution

STEP 1: Finding the cost price of $1$ dozen eggs when mixed together
Cost price of $2$ dozen eggs when mixed together $= 18 + 20 = R s . 38$
Cost price of $1$ dozen eggs when mixed together (C.P.) $= \frac{38}{2} = R s . 19$
STEP 2: Finding the gain percent when the eggs were sold at $₹ 23.75$ per dozen
Gain percentage $= (\frac{S P - C P}{C P}) \times 100 %$
Gain percentage $= (\frac{23.75 - 19}{19}) \times 100 %$
Gain percentage $= (\frac{4.75}{19}) \times 100 % = 25 %$
Hence, the gain percent when the eggs were sold at $₹ 23.75$ per dozen is $25 %$ .
