(1) 7.5%2)5%3) 10% (4) 20%.​

Answer 1

Given:

The selling price of an item is 19 times the loss

To find:

The loss percentage

Solution:

It is given that,

S.P. = 19 × Loss

⇒ S.P. = 19 [C.P. - S.P.]

⇒ S.P. = 19C.P. - 19S.P.

⇒ S.P. + 19S.P. = 19C.P.

⇒ 20S.P. = 19C.P.

⇒ S.P. = $\frac{19}{20} \times C.P.$

⇒ S.P. = 0.95 C.P. ..... (i)

Now,

The loss percentage is,

= $\frac{C.P. - S.P.}{C.P.}\times 100$

substituting the value of S.P. from (i)

= $\frac{C.P.\: -\: 0.95C.P.}{C.P.}\times 100$

= $\frac{0.05C.P.}{C.P.}\times 100$

= $0.05\times 100$

= $\bold{5\%}$ ← option (2)

Thus, the loss percentage is 5%.
