Question

A man sold two Transistors at Rs 990 each. On one he Gains 10%
and on another he loses 10% How much does he gain or lose
n the whole transaction?​

Answer 1

Answer:

In the 1st Transaction,

$profit\% = \frac{sp - cp}{cp} \times 100 \\ = > \frac{990 - cp}{cp} \times 100 = 10 \\ = > 990 - cp = 0.1 \\ = > 1.1 = 90 \\ = > cp = 900$

Now, at Loss 10 %.

$loss\% = \frac{cp - sp}{cp} \times 100 = 10 \\ = > \frac{cp - 990}{990} \times 100 = 10 \\ = > cp - 990 = 99 \\ = > cp = 990 + 90 = 1080$

Total CP = ₹( 900+1080) = ₹1980

Total SP = ₹ ( 990+990) = ₹1980

As CP = SP

So, there is neither gain nor loss.

Answer 2

Total CP = ₹( 900+1080) = ₹1980

Total SP = ₹ ( 990+990) = ₹1980

As CP = SP

So, there is neither gain nor loss.
