Question

a pen is listed at rs 800 and a discount of 30% is offered on the list price. what additional discount must be offered to the customer to bring the net price to rs 490

Answer 1

☆Hello friend☆

Discount%= 30
discount= 30 /100 ×800
= 240
SP= MP- DISCOUNT
SP= Rs (800-240)
= Rs 560

But we want SP to be Rs 490
Where MP is Rs 800
So discount must be offered
=Rs( 800- 490 )
= Rs 310
So extra discount must be offered=
Rs ( 310-240 )
= Rs 70
Additional %= 70/560 ×100
= 12 whole 1 by 2 %

Hope it helps

Answer 2

L.p = 800
D=30%
S.p after discount = 800 - 30 / 100 ×800
S.p= 560
Let second discount be d%
Therefore, 
560-d% × 560 =490
-d/100 ×560 = -70
d =(70  ×100)/ 560
d=12.5%
