Answer 1

Marked price = Rs 2000  if Successive discount of 15 % & 10 % is Rs 30 less than Single Discount of 25%

Step-by-step explanation:

Marked Price = M  Rs

Single Discount = 25%

Discount = (25/100)M = 0.25M

=> Price = M - 0.25M = 0.75M

Two successive Discount of 15%  & 10%

first Discount = 15%

First discount = (15/100)M = 0.15M

Price after first discount = M -0.15M =0.85M

Second discount = 10%

Discount =(10/100)*0.85M  = 0.085M

Price after second discount = 0.85M - 0.085M

= 0.765M

0.765M - 30  = 0.75M

=> 0.015M = 30

=> M = 2000

Marked price = Rs 2000
