Raul and his friends each of whom weighs 1/20 ton, are standing on a truck scale. The total weight shown is 3/4 ton.how can you find the total number of people on the scale?

Answer :

• Raul and his friends weigh 1/20 tons. (each of them).

,

• The total weight shown is 3/4 ton.

The total number of people on the scale (assuming not taking the weight of the truck) is:

[tex]\frac{total-weight}{\frac{1}{20}}=\frac{\frac{3}{4}}{\frac{1}{20}}=\frac{3\cdot20}{4}=\frac{60}{4}=15[/tex]

Therefore, the total number of people on the scale is 15 people.
