Answer:- $0.75 per kg and $0.50 per kg
let the price of sugar and rice be X and y respectively.
now ,
according to question,
3x + 2y = 3.25 $_____eq.(I)
2x + 2y = 2.50 $______eq.(II)
subtracting eq(II) from eq(I) , we get
2y will be cancelled and remains
X = 0.75 $
therefore , the price of sugar = 0.75 $ per kg.
and
substituting X = 0.75 in eq.(II) , we get
2*0.75 + 2* Y = 2.50
or, 2Y = 2.50- 1.50
or,. Y = 1/2= 0.5
hence , the price of rice is 0.5 $ per gram.
