Answer 1

LET CP OF 1 PEN=X
I.E. CP OF 16 DOZEN PENS=192X=TPTAL COST
AND SP OF 1 PEN=Y
I.E. SP OF 16 DOZEN PENS=192Y=TATAL SALE
AND SP OF 8 PENS=8Y=TOTAL LOSS
AS PER STATEMENT IN THE QUESTION, 192Y=192X-8Y
I.E. Y=96X/100
I.E. 8Y=768X/100
LOSS %=(768X)(100)/(100)(192X)=4%
NOW, CP OF 16 DOZEN PENS=576
I.E. 192Y=576-8Y
I.E.200Y=576
I.E. Y=288/100
I.E. 12Y=3456/100=34.56= SP OF 1 DOZEN PENS
