loss or gain per cent a)14 277%loss b)16 2/7% loss c)14
2/7% gain d)16 2/7% gain​

Answer 1

Step-by-step explanation:

answer is b)16 2/7% loss

Answer 2

Option 'd' is correct.

Step-by-step explanation:

Since we  have given that

cost price = 840 gm instead of 1 kg

So, it becomes $\dfrac{840}{1000}=0.84$

So, cost price = 0.84x

Loss%  = 4%

So, Selling price = $(100-4)x=96\%x=0.96x$

So, Profit would be

$0.96x-0.84x=0.12$x

So, Profit % would be

$\dfrac{0.12x}{0.84x}\times 100\\\\=\dfrac{1}{7}\times 100\\\\=\dfrac{100}{7}\\\\=16\dfrac{2}{7}\%$

Hence, Option 'd' is correct.
