for 50 KG- I will measure 9KG sugar with 7 & 2kg Weight. Now, with the help of 9 KG sugar, 7 & 2 KG weight, I will measure another 18 KG sugar. After this, I have one 18 KG sugar, 9KG sugar ( total sugar 27 KG) & two weight of 7 & 2kg respectively. I have to measure another 23 KG sugar ( to make it 50KG total). I will Place 18KG sugar+ 7KG weight on one side of beam balance & 2kg on another side ( 18+7-2= 23), now i can measure 23 KG sugar, making total sugar of 50 KG ( 9+18+23=50 )
