45 %  increase in rate at which he sold his sweets ​

Step-by-step explanation:

20 kilogram of sweets to sell.

Let say cost price per kg  = C  

Total Cost Price = 20C

Let say Selling price per kg = S

At the end of the day he could sell only 80% of his sweet

=> Sweets sold = (80/100) * 20  = 16 kg

=> Total Selling Price = 16S

Profit = 16S -  20C

Profit %  =  ((16S - 20C)/20C )  * 100 = 16

=> 80S - 100C  = 16C

=> 80S = 116C

=> S = 116C/80

=> S = 29C/20

Increase in rate = 29C/20 - C  =  9C/20

% increase in rate  = ((9C/20)/C ) * 100 =  45 %

45 %  increase in rate at which he sold his sweets ​
