Question

Shubha brought 100 eggs for rupees 50. Out of these 4 eggs found broken and he sold the remaning eggs at rate of 8.50 ruppes per doxen .find the gain or losd percent

Answer 1

cost of 100 eggs = 50

cost of 1 egg = 50/100 = 0.5

No of eggs remaining

= 100-4
= 96

SP of 12 eggs = 8.5

SP of 1 egg = 8.5/12

SP of 96 eggs
= 8.5 x 96/12
= 8.5 x 8
= 68

CP < SP

gain = SP - CP

= 68 - 50

= 18

% gain
= 18 x 100/50 %

= 36 %

Answer 2

sudha brought 100eggs for Rs.50
C.P=50 rupees
4eggs were broken
Left eggs=96
1 dozen =12 eggs
96 eggs=96÷12dozens
=8 dozens
price of 1 dozen eggs=Rs8.50
price of 7 dozen eggs=8.50×8
=68
gain=68-50
=18rupees
gain%=18÷50×100
=1800/50
=180/5
=36%
