Answer 1

hy good night dear...

Answer 2

SP = 8400 at 20% profit

so CP = x, let

x + 20% of x = 8400

x + 20x/100 = 8400

120x/100 = 8400

x = 840000/120

x = 7000

So CP1 = 7000

SP1 - CP1 = 1400 is the profit

Now CP2 = 8400 + 1400 in case of loss

So CP 2 = 9800

SP 2 = 8400

Loss = 9800 - 8400 = 1400

Loss% = 1400/9800 * 100 = 1/7 * 100 = 14 2/7%
