Question

If by selling a bed sheet for Rs 150, a person loses 4%. For what amount should he sell it so as to gain 20%​

Answer 1

Answer:

Let cost price= X and given selling price= 150

loss = 4% of cost price= 4 X /100

loss = cost price- selling price

4X/100 = X - 150

X/25 = X - 150

X - X/25 = 150

24X/25 = 150

X= 150 x 25/24= 625/4 = 156.25

cost price = 156.25

for 20%. gain selling price should be 156.25+156.25 × 20/100 =

156.25 + 31.25 = 187.50

Answer 2

Step-by-step explanation:

let cost price= X and given selling price=150

X= 150 x 25/24-625/4 = 156.25 cost price = 156.25

loss = 4% of cost price= 4 X/100

loss = cost price-selling price

4X/100 = X - 150

X/25=X - 150

X-X/25-150

24X/25 = 150

x

X= 150 x 25/24-625/4 = 156.25 cost price = 156.25

156.25 +31.25= 187.50 answer

for 20%. gain selling price should be 156.25+156.25 × 20/100 =156.25 + 31.25 = 187.50
