Question

kaloo ne 5 dozen egg 12 prati dozen ki dar se kharide unmein se 10 egg foot gaye aur shesh ko usne 18 rs prati dozen ke hisaab se sell kiye uska profit % or loss% batao

Answer 1

C.P of 1 dozen eggs = ₹12
C.P of 5 dozen eggs = ₹60
1 dozen = 12 eggs
5 dozen = 60 eggs
cost of 12 eggs =₹12
cost of 1 eggs =₹ 12/12=₹1
eggs left with him = 60-10=50eggs =4 dozen and 2 eggs
S.P of 1 dozen eggs = ₹18
S.P of 1 egg = ₹ 18/12
=₹3/2
S.P of 50 eggs = ₹3/2 × 50
=₹75
therefore gain = S.P-C.P
=₹(75-60)
=₹15
Gain% = Gain/C.P×100
= 15/60×100
=25%
