To Find :

a. Question can be answered by using any one of the 2 statements alone but not by the other alone

b. Question can be answered by using either of the 2 statements alone

c. Question can be answered by using the 2 statements together but not by either of the statements alone

d. Question cannot be answered by using the given statements​

Solution:

profit % on selling 60 pens

profit on selling 60 pens    is equal to SP of 20 pens

cost of 1 pen = C

Selling price of one pen = S

cost of 60 pens = 60C

Selling Price of 60 Pens = 60S

Profit  60S - 60C  = 20S

=> 40S = 60C

=> 2S = 3C

=> S = 3C/2

=> Hence profit %  = 50 %

CP of 1 pen is 2/3 of SP

=> SP  =  3x

=> CP = (2/3)3x = 2x

Profit %  = 100 * ( 3x - 2x)/2x  = 50 %

. Question can be answered by using either of the 2 statements alone
