Thanks! I am getting the answer as 0.454, is that what you got? option 1 seems to be the closest!

Answer is option 1?
Assuming volume of 5x7x9 (LCM from the different coffee blends ratio) of every coffee blend we get the following quantities-
Mix 1- A=2/5x5x7x9=126, B=3/5x5x7x9=189
Mix 2 A=2/7X5X7X9=90, C=5/7X5X7X9=225
Mix 3 A= 70 , D=245 (in a similar way)
Required ratio= (3/12x126+4/12x90+5/12x70)/(3/12x189+4/12x225+5/12x245)=0.404
