Question

a sofa set was sold for rupees 11520 after giving successive discount of 20% and 10% respectively what was the MP of the sofa set

Answer 1

SP = 11520

D1 = 20%

D2 = 10%

MP = 100/(100-D%) x SP

= 100/(100-20) x 11520

= 100/80 x 11520

= 14400

Now second discount

Mp = 100/(100-10) x SP

= 100/90 x 14400

= 16000

So MP was 16000 before two successive discounts
