Question

John spent 60% of his money on a notebook and 1/4 of the remainder on a pen the cost of the notebook is 65 pesos more than the pencil. How much money did he have at the beginning

Answer 1

Answer:

John had 130 pesos at the beginning.

Step-by-step explanation:

Let the total amount John had at the beginning be x pesos.

Amount spent on notebook is: $60\%of x=\frac{60}{100}\timesx=0.6x$

Remaining amount:  $x-0.6x=0.4x$

Amount spent on pencil:  $\frac{1}{4} of 0.4x=0.1x$

it is given that the cost of the notebook is 65 pesos more than the pencil.

That is,

$0.6x=0.1x+65\\0.5x=65\\x=130$

Thus, John has 130 pesos at the beginning.
