Since the question asks for the weight of the Liquid A, we should find the availability of Liquid A in the mixture. Logically the percentage does not change even when the gram raises.
8% of Liquid A in the 3 gram of R = 0.08*3=0.24
18% of Liquid A in the 7 gram of S = 0.18*7=1.62
Now we should turn this into part/total form.
1.5/10*100=15%
