Question

cp-300 and sp-400 formula

Answer 1

according to the question,
SP=400
CP=300

the SP is more than CP so it's a gain
gain=SP-CP
=400-300
=100
hence, the gain is 100

have a nice day

Answer 2

FORMULA = SP -CP
BCOZ SP IS GREATER THAN CP

SO WHEN SP IS GREATER THAN CP THERE IS A PROFIT OR GAIN.

SO, SP - CP
400 - 300
GAIN = 100
