Question

the price of sugar Rises by 25% by how much percent should a househoulder reduce his consumption of sugar, so as not to increase his expenditure on Sugar?​

Answer 1

Answer:

Let the original cost beRs100

After increase Rs.125

Then 125x (100-D)/100=100

100-D=100x100/125=80

100-D=80

D=100-80=20%

Reduce consumption by 20%

Answer 2

AnswEr :

$\boxed{ \bold{Reduction\% = \frac{Increase\%}{100 + Increase\%} \times 100 }}$

$\bold{Reduction\% = \large { \frac{25}{100 + 25} \times 100 }}$

$\bold{Reduction\% = \large{ \frac{25}{125} \times 100 }}$

$\bold{Reduction\% = \large \frac{1}{5} \times 100}$

$\large\bold{Reduction\% = 20\%}$
