Question

A old radio set was brought for rupees 780 and rupees 220 was spent on its repair it was sold for rupees 990. find the spent or loss % ?​

Answer 1

C.P. = rupees 780

Net C.P. = rupees 780 + rupees 220

= rupees 1000

S.P. = rupees 990

Loss = C.P. - S.P.

= rupees 1000 - rupees 990

= rupees 10

Loss PerCent = Loss/C.P.*100 PerCent

= rupees 10 / rupees 1000 * 100 PerCent

=1 PerCent

5)S.P. = rupees 31040

Loss = rupees 908

C.P. = S.P. + Loss

= rupees 31040+ rupees 908

= rupees 31948

Answer 2

Solution:-

Amount of money a old radio set was bought= Rs.780

Amount of money spent on it's repair = Rs. 220

Amount of money he sold the radio = Rs. 990

∴ Total money spent for radio

= Rs. 780 + Rs. 220

= Rs. 1,000

Therefore, Loss since, C.P. is greater than S.P.

Loss = ( Rs. 1000 - Rs. 990 )

= Rs. 10

∴ Loss = Rs. 10

Step-by-step explanation:-

Now, let's find loss percentage,

We know that,

$\boxed{ \boxed{ \tt{Loss \% = \: \dfrac{Loss}{C.P.} \times 100}}}$

By putting the values,

$\longrightarrow \: \dfrac{10}{1000} \times 100$

Dividing 1000 and 100 with 100

$\longrightarrow \: \dfrac{10}{10}$

Cancelling the 0s.

$\bf{ \longrightarrow \: 1\%}$

Therefore, Loss% is 1%

Remember:-

• If C.P. > S.P. then, there will be loss.

• If S.P. > C.P. then, there will be profit.

• Gain = S.P. - C.P.

• Loss = C.P. - S.P.
