Due to 20% reduction in price, a man can buy 2 kg more sugar for Rs. 60. Original price per kg: MCQ with Answer and Explanation

Original x, xy=60. 0.8x(y+2)=60 → 48 + 1.6x =60 → 1.6x=12 → x=7.5? Wait: 0.8x(y+2)=0.8xy + 1.6x =0.8*60 + 1.6x =48+1.6x=60 → 1.6x=12 → x=7.5, not 6. So if x=7.5, original price 7.5, reduced 6. So reduced price 6. So I'll ask reduced price: 6. Or ask original 7.5. Options given: 5,6,7.5,8. So correct answer 7.5. So original price Rs.7.5.
