Question

Pradeep sold two pairs of rupees thousand one on one he gains 10% and on the other He loses 10% find the gain or loss percent in the whole transaction

Answer 1

$\huge\boxed{\texttt{\fcolorbox{Red}{aqua}{Hello Friend}}}$
For I transaction
SP = Rs 1000
Profit = 10%
CP = SP x 100/(100+profit%)
$= \frac{1000 \times 100}{100 + 10} \\ = \frac{100000}{110} \\ = 909.09$
Now
For II transaction
SP = Rs 1000
LOSS = 10%
CP = SP x 100/(100-loss %)
$= \frac{1000 \times 100}{100 - 10} \\ = \frac{100000}{90} \\ = 1111.11$
FOR WHOLE TRANSACTION

Total SP = 1000 + 1000 = 2000
Total CP = 909.09 + 1111.11 =2020.20

SINCE SP IS LESS THAN CP SO THERE IS LOSS IN THE TRANSACTION

LOSS = CP - SP
= 2020.20 - 2000
= Rs 20.20
Loss% = Loss x 100 /CP
$= \frac{20.20 \times 100}{2020} \\ = \frac{2020}{2020} \\ = 1\%$
So There is Loss of 1% in the whole transaction

Answer 2

Hey mate ^_^

Answer:
=======

C.P of shoe pair A in 1000+100

(10% of 1000) =Rs.900

C.P of shoe pair B in 1000+100

(10% of 1000) =Rs.1100

If Pradeep had sold the shoe pairs at their normal prices, then the total cost would have been 1100+900 rupees = 2000 rupees

He sold the shoes, at both 1000 rupees so their cost was 1000+1000 rupees = 2000 rupees

So, in both the cases, the cost would be the same with no loss or gain%.
