Question

divide 80 among 3 people so that the second will have twice as much as the first, and the third will have 5 less than the second

Answer 1

Given,

Total amount = 80

Number of people = 3

The second people will have twice as much as the first, and the third will have 5 less than the second.

To find,

The amount that each one of them get.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

First people gets = x

Second people gets = 2×x = 2x

Third people gets = 2x-5

According to the data mentioned in the question,

x+2x+2x-5 = 80

5x-5 = 80

5(x-1) = 5×16

x-1 = 16

x = 17

First people gets = 17

Second people gets = 17×2 = 34

Third people gets = 34-5 = 29

Hence, the amounts of first,second and third people are 17,34 and 29 respectively.
