Answer 1

Step-by-step explanation:

you have been given a physical balance and 7 weights of 47,46,43,48,49,42 and 77 kgs keeping weights on one pan and object on the other ,what is the maximum you can weight less than 178 kgs?

as question says weight on one pan and object on other pan

49 + 48 + 77 = 176 kg is max

if we use freedom to put weight on both pans

49 + 48 + 77 + 43 -42 = 177 kg

49 + 48 + 77 + 47 - 46 =.177 kg

46 + 47 + 77 + 49 - 42 = 177 kg
