Question

In a sale, a shop
reduces all its prices by 15%. Calculate:
(ii) the original price of an article which was sold for Rs 20.40.

Answer 1

It is given that
Rate reduction $=15$%
(ii) Sale price $=Rs20.40$
Rate of reduction $=15$%

We know that

Cost price = $(SP\times 100)$/ (100 - reduction %)

Substituting the values

= $(20.40\times 100)/(100-15)$

By further calculation

= $(2040\times 100)/(100\times 85)$

$=Rs24$
