Question

Rahul bought a sweater and saved rs. 20 when a discount of 25% was given. What was the price of the sweater before the discount?

Answer 1

Let, Before Discount amount be Rs 100,
and After Discount amount is Rs 75.

So, solving by Unitary Method,
Rs 25 is saved when the amount is Rs 100,
Re 1 is saved when the amount is Rs $\frac{100}{25}$
Rs 25 is saved when the amount is Rs $\frac{100}{25}$ × 20
                                                   = Rs 80

Answer 2

Rahul saved a sweater = 20

And discount given = 20*25/100

=5

Price for before discount then 1% of % will be multiplied are to be =20*100/25 = 80
