Question

find a single discount equivalent to two succesive discount of 20% and 5%​

Answer 1

Step-by-step explanation:

Let the marked price =Rs100

After a discount of 20%, the price = 100−20% of100 = 100−

100

20

×100 = 100−20=80

After a further discount of 5%, price = 80−5% of80 = 80-5/100

×80 = 80−4 = Rs76

Final Selling = Rs76

Total Discount = 100−76=Rs24

Thus, discount % =

100

24

×100 = 24%

Answer 2

Answer:

Let MP be =₹100

sp=MP×(100-d1%/100)(100-d2%/100)

=100×(100-20/100)(100-5/100)

=100×80/100×95/100

=80×95/100

=7600/100

=76

NOW, single discount equivalent to successive discount 20% and 5% is= 100-76=24%
