Answer 1

Given:

Half of Baker's life was over when he got the degree and afterwards spent 1/5 of his life working for big hotel.

To Find:

How old was he

Solution:

• Let the life of Baker be x.
• So, half of his life is over as he got his degree.
• This will be formulated as: x- 1/2. - eqn.(1)
• Then he spent 1/5 of his remaining life spent working for big hotel.
• Then, it will be formulated as: ( x - 1/2 ) * 1/5 - eqn.(2)

∴ By putting the equations together, we get:

x = (x - 1/2) * 1/5

⇒ x = x - 1/2 ÷ 5

⇒  5x = x - 0.5

⇒  5x - x = - 0.5

⇒  4x = - 0.5

⇒  x = - 0.5 /4

⇒  x = - 0.125.

*Note: This is a faulty question as the answer is having a (-) negative value.

The question may also be incomplete. These kind of questions should provide certain information regarding formulation of equations.
