The difference between a discount of 40% on 500 Rs. and two successive discounts of 30% and 10% on the same amount is :
[A]0 Rs.
[B]10 Rs.
[C]15 Rs.
[D]20 Rs.
15 Rs.
Single equivalent discount of two consecutive discount of 30% and 10%.
$latex = 30+10-\frac{30\times 10}{100} = 37\%&s=1$
∴ Required difference = 40% of 500 – 37% of 500
$latex = 500\times \frac{3}{100} = 15\ Rs.&s=1$
Hence option [C] is correct answer.
