Answer 1

Given
Total quantity sold =65kg
Rate =9.25/kg

Sp of 65kg =65x9.25=601.25

According to the question he get profit of ₹ 16.25

Profit =sp-cp

Cp=sp-profit

Cp=601.25-16.25

Cp=₹585

Cp of 65kg=585

Then cp of 1 kg =585/65=₹9

Answer 2

total weight= 65

sp of 1 kg = 9.25

sp of 65 kg sugar=9.25×65

= 601.25

then profite earned = 16.5

profit =sp of 65 kg sugar-cp of 65 kg sugar

16.25=601.25-cp of 65 kg sugar

cp of 65 kg sugar=601.25-16.25

CP of 65 kg sugar=585

so,

cp of 1 kg sugar= 585/65

=117/13

= 9

hence,

cp of 1 kg sugar = 9
