ANSWERS KEY:
1- (a)
2- (a)
CP : MP = 2 : 3
Let CP = 200, SP = 300
% profit : % discount = 3x : 2x
ATQ,
3x/100*200+2x/100*300 = 100
x = 8.33%
Discount = 2x = 16.66%
3- (b)
Let the MP = Rs.1 per kg then
weight   MP        Rate
100      100        1
96       80/SP      80/96
Effective discount = 1-80/96 = 16/96
% discount = 16/96*100 = 16.66%
