Answer:
let the original price be X
reduced rate = 90%of x per kg
= X × 90/100 per kg
= 9/10x per kg
quantity of sugar for ₹ 279 at the original rate = 279/X kg
quantity of sugar for ₹279 at the new rate = 279/9/10x kg = 279×9/10
= 251.1 kg
= 279/X - 251.1/X = 6.2
= 6.2 X= 279-251.1
= 6.2 X =27.1
= 4.37 ₹ per kg
reduced rate = 9/10× 4.37
= ₹ 3.933
