Answer 1

Answer:

M.P=Rs.8400

sp=mpx(100-Dis) /loo

6426=8400 (100-Dis)/ 100

100-Dis=6426x100/8400

= 76.5

Discount = 100-76.5=23.5%

To find second discount

Ist. Disc=15% (Data)

-15-x+15xX/100=23.5

multiply by loo

-15oo-loox+15x=2350

1500-85x=2350

85x=850

x = 850/85=10

2nd discount is 10% Ans
