PLEASE MARK ME AS BRAINLIEST

Step-by-step explanation:

Reduction=20% ,    means x=20

increased Quantity= (x/100-x)*100

                              = (20/100-20)*100

                              =25%

25%=2.5 KG

100%=10 KG

10 KG=RS 160

PER KG=RS 16

Answer 2

${\huge {\underline {\red {\mathfrak {Answer}}}}}$

Let initial price of 100 kg Sugar was Rs. 100.

Now, 20% decrease in rate then rate of 100 kg sugar would be Rs. 80.

So,

Rs. 80 = 100 kg sugar.

Rs. 1 = 10080 kg sugar.

Rs. 100 = 100×10080

= 125 Kg sugar.

Increment in sugar = 25 kg.

% increment = 25×100100

= 25%.

Means 20% rate decrease, 25% of consumption increase.
