A<B
Explanation:
We are supposed to compare A and B as an inequality.
We are given 120% of A = 150
and 105% of B = 165
Dividing the two we get A:B = (150x105):(165x120) = 105:128
which clearly shows the ratio of A to B which helps in comparing the values of A and B and clearly, value of A is less than that of B.
So, the inequality is A is less than B.
Hence, A<B is the required answer.
