Question

Jaya sold two sarees for₹2185 each. on one saree she lost 5%. Find her gain loss perc6 on the whole transaction.​

Answer 1

Given,

S.P (1 saree) = Rs. 2185

Case I:

S.P of one saree = 2185

loss = 5%

\begin{lgathered}C.P = \frac{100}{100-loss\% } \times S.P \\C.P = \frac{100}{100-5} \times 2185\\C.P = 2300\end{lgathered}

C.P=

100−loss%

100

×S.P

C.P=

100−5

100

×2185

C.P=2300

Case II:

S.P = 2185

gain = 15%

\begin{lgathered}C.P = \frac{100}{100+profit \%} \times S.P\\ C.P = \frac{100}{100+15} \times 2185\\C.P = 1900\end{lgathered}

C.P=

100+profit%

100

×S.P

C.P=

100+15

100

×2185

C.P=1900

Now,

Total S.P = 4370

Total C.P = 1900 + 2300

= 4200

Gain = S.P - C.P

= 4370-4200

= 170

Gain % = gain/C.P x 100

= 170/4200 x 100

= 4.04 %

Hence, Jaya's gain percentage on the whole transaction is 4.04%
