Question

A man buys 5 dozen eggs at Rs.36 per dozen. Out of which 5%got broken . He sold the remaining eggs for RS. 48 per dozen. What was his total gain

Answer 1

cp of one dozen of eggs,12eggs=Rs36
cp of five dozen of eggs, 60eggs=Rs36x5=Rs180
% of eggs broken = 5%
No of eggs broken = 5/60x100=3
no of eggs remaining = 60-3=57
now,
sp of one dozen of eggs,12eggs =Rs48
sp of one egg = Rs48/12= Rs4
sp of 57 eggs= Rs4x57=Rs228
now,
total gain = Rs228-180= 48
