Answer is D. 320

suppose the bags contain only raisins and peanuts are x, therefore,

bags only have almonds are 20x,

bags only have peanuts are 4x,

bags only have raisins are 40x,

suppose the bags that have almonds in it and have more than one item are t,

therefore t+20x=210

then we have this: 40x+x+4x+20x+t=435

x=5

so: the bags have only one item in it are: 40x+4x+20x=64x=320
