This is an Alligation problem,
So 1:30= 0.03
1:10= 0.1
1:50=0.02
Now solve the problem:
.03 - 02 =.01
.1 - .03= .07
Total part .08
So 480ml of 1:30 is:
480*.07/.08=420 ml 6 parts
480*.01/.08= 60 ml. 1 part
To make 480ml of 1:30 we have to add 7 parts of 1:50 and 1 part of 1:10 that's how we get our answer
