Question

Arvind sold 10 dozen eggs for rupees 230 if he owns a profit of rupees 40 at what price did he purchase the 5 dozen eggs

Answer 1

cp of 10 dozen = rs230
1 dozen=12
10 dozen=10×12=120
sp of 120 eggs = rs230
cp = sp-cp
cp= 230-40=190
cp of 5dozen(60) eggs
cp of 10 dozen = 190
so cp of 5 dozen =190÷2=95
answer = 95

verification
95×2=190
190+40=230
