Answer:
(1)- Since CP<SP
It is a gain
Gain= SP-CP
= 713-620
= 93
Gain %= Gain/CP×100
=93/620×100
= 15 percent
(2)- SinceCP>SP
It is a gain
Gain=SP-CP
=372.60-345
=27.60
Gain%= Gain/CP×100
= 27.60/345×100
= 8 percent
(1)- SP=CP+Gain
= 1650+4%of CP
= 1650+(4/100+1650)
= 1650+(33+2)
= 1650+66
= 1716
SP= 1716
