Question

A radio is sold for rs.990 at a profit of 10%. what would have been the actual profit or loss on it, if it had been sold for rs.890?

Answer 1

sp = 990 p = 10%
cp = 990×100/110 = rs900
sp = 890
loss = 900-890 = rs 10

Answer 2

Answer:

Actual loss = Rs 10

Step-by-step explanation:

Given ,

i) Selling price of a radio (s.p)=Rs 990

profit (g)=10%

Let the cost price = c.p

$\boxed {c.p=\frac{s.p\times 100}{100+g}}$

$\implies c.p=\frac{990\times 100}{100+10}\\=\frac{990\times 100}{110}\\=Rs\:900$

$Now,\\ii)\:c.p=Rs\:900,\\s.p=Rs\:890$

$c.p > s.p$

He gets loss.

Loss = c.p - s.p

= Rs 900 - Rs 890

= Rs 10

Therefore,

Actual loss = Rs 10
