Step-by-step explanation:
SP for 1 Pen= 99
Loss%=10%
THEREFORE COST PRICE =SP×100÷(I00-LOSS%)
=99×100÷(90)
=9900÷90
=110
SP FOR 2nd PEN=99
GAIN% =10%
THEREFORE COST PRICE
=SP ×100÷( 100+PROFIT %)
=99×100÷(110)
=90
TOTAL SP= 99+99
=198
TOTAL CP= 110+90
=200
Since CP is Greater than SP
Therefore there is LOSS
Loss= CP - SP
=200-198
=2
Loss%=( Loss÷CP)×100%
=1% ANSWER
