Q

Why should we equalise the marginal utility per dollar?

A

Move money from G1 to G2 if it increases the utility by more than it decreases the utility from G2. Buying more of G1 decreases marginal utility, and buying less of G2 increases its marginal utility, so gap between marginal utility per dollar decreases.
