Answer 1

Answer:

please mark me as brianlisted

Step-by-step explanation:

It is given that

S.P of an article = Rs.770

Loss=Rs.110

We know that

C.P.=S.P.+loss

Substituting the values

=770+110

=Rs.880

Here

loss % =[LOSS/ C.P × 100]%

Substituting the values

=[110/880×100]%

By further calculations

=100/8 %

So we get

=25/2

12.5

Answer 2

Answer:

Rs 1320

Step-by-step explanation:

Given,

The selling price of a watch is Rs $770$.

It was sold at $30%$% loss.

We know that,

Cost Price - Selling Price = Loss

Let the Cost Price be $x$.

⇒$x-770=\frac{30}{100} x$

⇒$\frac{70}{100} x=770$

⇒$x=Rs 1100$

Hence, the cost price of the watch is Rs $1100$.

We need to find the Selling Price when the watch is sold at a profit of $20$%.

Hence, the profit will be $20$% of Rs $1100$.

$=\frac{20}{100} *1100$

$=220$

Hence, the profit is Rs $220$.

So, the selling price is,

$=1100+220\\=1320$

Hence, the watch should be sold at Rs $1320$ to gain $20$%.
