No information of customers who neither used A or B
Combining both

Let neither = 10 then
100= A+70-20+10
A=40-------> only A = 40-20=20

But if neither = 20
100= A+70-20+20
A=30-------> only A = 30-20=10

then both are insuff

Minimum number of ppl using soap a is 20
Maximum number of ppl using soap a could be 30.Out of which we are not sure about the remaining 10. Whether they are users of soap a for certain or if they use neither a nor b.
