Answer:

Let original cost of sugar was =Rs x per kg.

Reduced cost of sugar = Rs (x-20x/100)= Rs. (4x/5) per kg.

Quantity of sugar for Rs 600 @ Rs x per kg. =(1/x)×600 kg.

Quantity of sugar for Rs 600 @ Rs (4x/5) per kg =(5/4x)×600 kg. , acordingly:-

(5/4x)×600 - (1/x)×600= 5

or. 600(5/4x-1/x)=5

or. 600×(1/4x)=5

or. 20.x= 600. or. x= 600/20= 30.

Thus , the original cost of sugar was Rs 30 per kg. Answer.
