Question

On increasing the price of an article by 16%, it becomes Rs 1479. What was its original price?

Answer 1

Consider the original price of an article = Rs x
$1479=(1+16/100)$ of original price
It can be written as
$1479=\left[(100+16)/100\right]\times Rsx$
By further calculation
$1478=116/100\times x$
So we get
$116x/100=1479$
By separating the terms
$x=(1479\times 100)/116$
$x=(1479\times 25)/29$
By division
$x=51\times 25$
$x=1275$
Therefore, the original price of an article is Rs 1275.
