Question

A blanket after 20% discount costs Rs.432. Whats was the original price before discount?

Answer 1

Solution :

Let the Original price of

the blanket = Rs x

discount (d) = 20%

Selling price (s.p) = Rs 432

Original price

= ( s.p × 100 )/( 100 - d )

= ( 432 × 100 )/( 100 - 20 )

= ( 432 × 100 )/80

= 54 × 10

= Rs 540

Therefore ,

Original price of the

blanket = Rs 540

Answer 2

$let \: the \: oriinal \: prive \: of \: a \: blanke \: be \: x \: \\ therefore \: discount \: = \: x \times 20 \div 100 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 20x \div 100 \\ \\ \\ orignal \: price \: = discouted \: prive \: + discount \: \\ x = 432 + \frac{20x}{100} \\ x = \frac{43200 + 20x}{100} \\ 100x = 43200 + 20x \\ 100x - 20x = 43200 \\ 80x = 43200 \\ x = \frac{43200}{80} \\ x = 5400 \\ therefore \: the \: original \: price \: of \: the \: blanket \: is \: rupees \: 5400$
