Answer:
Okay so first you need to divide price by the amount/value -) 300/5
= RS 60
That means Rs 60 is for a KG (1 kg = 1000g)
The rate of 3 kg = Rs for 1 kg x kg
= 60 x 3
= Rs 180
A kg is 1000g
So 750g or 0.75kg = 3/4 of a kg
Rs for 750g = 3/4 of 60 or 3/4 x 60
= 45
Price of 3 kg = Rs 180
Price of 750g or 0.75kg = Rs 45
Price of 3 kg and 750 g = Rs 180 + 45
= Rs 22
