Answer:

Let original rate = Rs. X per kg

New rate = 79% of Rs. X per kg

= Rs. (79 * X)/100) per kg

Now,

{(100/79X)/100} - {100/X} = 10.5

Or, 10000/79X - 100/X = 10.5

Or, 10000 - 7900 = 10.5 * 79X

So, X = 2100/(10.5 * 79)

Thus, X = 2100/(10.5 * 79)

Reduced rate = Rs. (79/100) * 2100/(10.5 * 79) per kg = Rs. 2 per kg.
