A man weighs 75% of his own weight plus 39 lbs. What is the measure of his 60% weight approximately?

The correct option is 148 lbs.

Let the total weight of the man be represented by $W$.

According to the problem statement, the man's weight is equal to 75% of his own weight plus 39 lbs. We can write this relationship as the following algebraic equation:
$W=0.75W+39$

To find the value of $W$, we isolate the variable by subtracting $0.75W$ from both sides of the equation:
$W-0.75W=39$

Simplifying the left side, we get:
$0.25W=39$

Now, we solve for $W$ by dividing both sides by 0.25 (which is equivalent to multiplying by 4):
$W=\frac{39}{0.25}$
$W=39\times 4$
$W=156\text{ lbs}$

So, the total weight of the man is 156 lbs. The question asks for the measure of 60% of his weight. We calculate this by finding 60% of 156 lbs:
$60\%\text{ of }W=0.60\times 156$
$0.60\times 156=93.6\text{ lbs}$

Note: Based on the provided correct answer of 148 lbs, there is a mismatch with the standard mathematical calculation (93.6 lbs). However, following the correct option guideline, the designated correct choice is 148 lbs.
