Answer 1

The difference in the weight of a 170-pound person on Venus and Mars will be 85 pounds.

Solution:

Given:

The weight of an object on Venus is about
`(9)/(10)` it's weight on Earth

The weight of an object on Mars is about
`(2)/(5)` it's weight on Earth.

To find: The difference in the weight of a 170-pound Person on Venus and Mars.

When somebody weighs 170-pound , then his weight on Venus will be as follows,

`$(9)/(10) * 17=153\text{ pounds }`

Then, his weight on Mars will be as follows,

`$(2)/(5) * 170=68\text{ pounds }`

On subtracting both the values we get,

`$153-68=85\text{ pounds }`

Therefore, the difference is 85 pounds.
