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 / 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
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%
