A household earns $3,200 a month. Rent takes one quarter of that, food costs $480, and other expenses come to $650. How much is left?

Correct answer to question 43 (Arithmetic Reasoning): $1,270

Method

Convert the fraction to a dollar figure before subtracting. Rent is one quarter of 3,200, or $800, and the three expenses total 800 + 480 + 650 = $1,930, leaving 3,200 - 1,930 = $1,270.
