Answer / aravind k
Intitally take 100 , 20% of 100 gives 80
25% of 80 gives 60
10% of 60 gives 54.
therefore 100 -54=46.
46 might be the answer.

Answer / parameshwar appi
net discount=a+b-(ab/100)
answer is 46
20 and 25 net discount is 20+25-(25*20/100)=40
similarly 40 and 10 is 40+10-(40*10/100)=46%

Answer / isha trivedi
100-20=80
100-25=75
100-90=90
now assume that the discount is given out of 100
so 80*75*90/100*100*100=0.54
so the one equivalent discount will be 1-0.54=0.46x100=46%

Answer / uday
let the value of the product be =x
after 20%discount the value becomes=x-(.2x)=.8x
now 25%discount on this value is given by=(.8x)(1-.25)
another 10%discount gives the cost as =(.8x)(1-.25)(1-.10) so the final cost is .54x
hence discount =1-.54=.46
that is 46% discount

Answer / ranjit kumar
formula for successive discount
(a+b)-(ab/100)
for 20% and 25% (20+25)-(20*25/100)=45-5=40%
similarly for 40% 10% (40+10)-(40*10/100)=50-4=46%
Hence Ans is D) 46%
