Answer:
MP=(-60)
Step-by-step explanation:
Discount%=15%
Profit=Rs.10
now,
SP=MP-D% of MP
=x-15/100*x
=11x/20
now,
CP=11x/20-10
CP=(11x-200)/20...........equation i
again,
Discount%=25%
Loss=Rs.2
now,
SP=MP-D% of MP
=x-25/100*x
=3x/4
Loss=CP-SP
2=CP-3x/4
2+3x/4=CP
CP=8+3x/4............equation ii
Finally,
CP=CP
(11x-200)/20=8+3x/4
44x-800=160+60x
44x-60x=160+800
-16x=960
x=(-60) answer
