Answer 1

Step-by-step explanation:

Given:

• Two successive discount

To Find:

• Equivalent discount of two successive discount

Formula Used-

$\tt\leadsto SP = MP (1 - \frac{d _{1} }{100} )(1 - \frac{d _{2}}{100} )$

Solution:

Let MP be Rs 100

SP=100(1-10/100)(1-20/100)

SP=100×9/10×⅘

SP=Rs.72

Discount=SP-MP

=100-72

=Rs.28

Discount%=Discount/MP×100%=28%.
