Question

By selling a wooden table at a loss of 20%, a shopkeeper makes a loss of 90. Find its
(1) selling price (ii) cost price.​

Answer 1

Solution :-

Let the cost price be x

It is given that,

By selling a wooden table he had a loss of 20% that is Rs 90

Now,

As we know that,

Loss % = Loss/CP * 100

Subsitute the required values,

20 = 90/x * 100

20x = 9000

x = 9000/20

x = 450

Thus, The Cost price of the wooden table is Rs.450

2) Now, we have to find the SP

Therefore,

we know that,

CP - SP = Loss. [ CP > SP ]

Subsitute the required values,

450 - SP = 90

450 = 90 + SP

SP = 450 - 90

SP = 360

Hence, The selling price of the wooden table is Rs 360 $.$

Answer 2

Answer:

(i) Selling price = 360

(ii) Cost price = 450

Step-by-step explanation:

Given -

By selling a wooden table,

Shopkeeper makes a loss (in %) = 20%

Loss = 90

To find -

The selling price (S.P.)

And the cost price (C.P.)

Solution -

We will find Cost price first, Let us think cost price as x

We know that

Loss% = loss × 100/C.P.

20% = 90×100/x

=> 20x = 9000

=> x = 9000÷20

=> x = 450

It means Cost price = 450

Now we have found the cost price, then we will find the selling price (S.P.)

As we know that shopkeeper makes a loss and

loss = C.P. - S.P.

=> 90 = 450 - S.P.

=> S.P.+90 = 450

=> S.P. = 450-90

=> S.P. = 360

It means Selling Price = 360

Hope it helps.
