This money puzzle starts with $700 and gives you two instructions: remove half, then add $70.
The correct answer is $420.
Half of $700 is $350. If you remove that amount, you are left with $350. Then add $70.
$350 + $70 = $420.
So the complete calculation is: $700 − $350 + $70 = $420.
The wording may make the puzzle sound like a trick, but the simplest reading works. Find half of the original amount, subtract it, and then perform the final addition. Following the steps in order makes the answer clear.
