Answer 1

64.000288% Approx 64 percent

Step-by-step explanation:

Let sp = 100

Mp=? by giving successive 40%, 25%, 20%

100–40=60, 100–25=75, 100–20=80

Mp= (100/60 *100)*(100/75 )*(100/80)

Mp =277.78

Discount = MP-SP

Total discount : 277.78 - 100 ie: 177.78

Single discont be X

X% of MP = total discount

277.78*x/100=177.78

X=64.000288%

Single discount = 64.000288% Approx 64 percent
