Question

When a pen is sold at a discount of 15% there is a gain of rs 10 but if it is sold at 25% discount there is a loss rs 2 find mp

Answer 1

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
