Question

A man sold a cooler for ₹4500 at a loss of 25%.For what amount should he sell the cooler to gain 25%?

Answer 1

Answer:

When a plot is sold for Rs. 18,700, the owner loses 15%. At what price must that plot be sold in order to gain 15%?

Ans Let us first find out the c.p of the plot

Let c.p = 100

Loss =15%

s.p = 100 - 15 = 85/

Applying unitary method

If s.p is 85 than c.p is =100

If s.p is 1 than c.p is = 100/85

If s.p is 18700 than c. p = (100/85) ×18700 = 22000/-

Now he wants gain of 15% on 22000

15%of 22000 = (15/100) × 22000 = 3300/-

Therefore he must sell the plot at

= 22000 + 3300 = Rs 25300/- Ans

Answer 2

Answer:

Step-by-step explanation:

Let c.p = 100

Loss =15%

s.p = 100 - 15 = 85/

Applying unitary method

If s.p is 85 than c.p is =100

If s.p is 1 than c.p is = 100/85

If s.p is 18700 than c. p = (100/85) ×18700 = 22000/-

Now he wants gain of 15% on 22000

15%of 22000 = (15/100) × 22000 = 3300/-

Therefore he must sell the plot at

= 22000 + 3300 = Rs 25300/- Ans
