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%
