Question

Find profit or loss percent.
1. C.P = 600, S.P. = 630
2. C.P. = 2220, S.P = *1776
3. C.P. = 740, S.P. = 629
4. C.P. = 950, S.P. = 1026
5. C.P. = 250, S.P. = 34​

Answer 1

★ Solution:-

1. C.P. = 600 , S.P. = 630

Answer:

Since, S.P. > C.P, so profit

Therefore,

$Gain\% = \bigg( \: \dfrac{Gain}{C.P.} \times 100 \: \bigg)$

Profit = Rs. 630 - Rs. 600

= Rs. 30

$= \dfrac{30}{600} \times 100$

$= \dfrac{30}{6}$

$\boxed{ = 5\% \: gain}$

2. C.P. = 2220, S.P = 1776

Answer:

Since, C.P. > S.P. so loss

$Loss\% = \bigg( \: \dfrac{Loss}{C.P.} \times 100 \: \bigg)$

Loss = Rs. 2220 - Rs. 1776

= Rs. 444

$= \dfrac{444}{2220} \times 100$

$= 0.2 \times 100$

$\boxed{ = 20\% \: loss}$

3. C.P. = 740, S.P. = 629

Answer:

Since, C.P. > S.P. so loss

$Loss\% = \bigg( \: \dfrac{Loss}{C.P.} \times 100 \: \bigg)$

Loss = Rs. 740 - Rs. 629

= Rs. 111

$= \dfrac{111}{740} \times 100$

$= 0.15 \times 100$

$\boxed{ = 15\% \: loss}$

4. C.P. = 950, S.P. = 1026

Answer:

Since, S.P. > C.P, so profit

$Gain\% = \bigg( \: \dfrac{Gain}{C.P.} \times 100 \: \bigg)$

Profit = Rs. 1026 - Rs. 950

= Rs. 76

$= \dfrac{76}{950} \times 100$

$= 0.08 \times 100$

$\boxed{ = 8\% \: profit}$

5. C.P. = 250, S.P. = 34

Answer:

Since, C.P. > S.P. so loss

$Loss\% = \bigg( \: \dfrac{Loss}{C.P.} \times 100 \: \bigg)$

Loss = Rs. 250 - Rs. 34

= Rs. 216

$= \dfrac{216}{250} \times 100$

$= 0.864 \times 100$

$\boxed{ = 86.4\% \: loss}$

★ More Info ★

$\bull \: Gain = S.P. - C.P.$

$\bull \: Loss = C.P. - S.P.$

• When C.P. and gain% are given,

$\: S.P. = \dfrac{(100 + gain\%)}{100} \times C.P.$

• When C.P. and loss% are given,

$\: S.P. = \dfrac{(100 - loss \: \%)}{100} \times C.P.$
