Answer»

let the actual price be X

so, first discount is 20% , so the price becomes x-(20%ofx) => x-0.2x = 0.8x

now of the price of 0.8x , another 15% discount is there.. so, again the price drops to

= 0.8x -(15% of 0.8x) = 0.8x-0.12x = 0.68x

so, total discount on initial price is = (x-0.68x)×100%/x = 0.32*100 = 32%
