List price of an article at a show room is 2000 Rs. And it is being sold at successive discounts of 20% and 10% . Its net selling price will be :
[A]1400 Rs.
[B]1440 Rs.
[C]1900 Rs.
[D]1700 Rs.
1440 Rs.
Equivalent discount for successive discounts of 20% and 10%
$latex = \left ( 20+10-\frac{20\times 10}{100} \right )\% = 28\%&s=1$
∴ Net selling price = 72% of 2000
$latex = \frac{72\times 2000}{100}&s=1$ $latex = 1440 Rs.$
Hence option [B] is the right answer.
