Question

Find the single discount to three discounts of 40% , 60% and 80%.​

Answer 1

Answer:

Let the price be x

Formula of mp=(1-d1/100)(1-d2/100)(1-d3/100)×cp

=(1-40/100)(1-60/100)(1-80/100)x

=60/100×40/100×20/100x

=3/5×2/5×1/5x

=6x/125

since,d=cp-mp

=x-6x/125

=119x/125

Now,Since d%=d/cp×100

=119x/125÷x ×100(x got cancelled)

=119/125×100

=95.2% Answer........
