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.
