+1886 SHOW ALL WORKING OR YOUR ANSWER WILL BE WRONG BECAUSE I SAID SO.
Rice is sold in 75-gram packs and 120-gram packs.
The masses of both packs are given correctly to the nearest gramme.
Calculate the lower bound for the difference in mass between the two packs.
+36916 Agreed,,,I guess the question needs to specify what limits of rounding are ( you could go to 75.499999999999999...) and what practical weight measurements are available in manufacturing and packaging ! I felt 100mg was 'practical' LOL
+36916 75 grams can be UP to 75.4 or as LOW as 74.5 and still be rounded to 75 gm
120 UP to 120.4 LOW as 119.5 120
120.4 - 74.5 = max diff = 45.9
MIN diff = 119.5 - 75.4 = 44.1 gm
+118609 EP I think the bottom one should go up to 75.4999999 = 75.5
Rice is sold in 75-gram packs and 120-gram packs.
74.5 to 75.5 119.5 to 120.5
lowest possible difference = 119.5 - 75.5 = 120-75-1 = 44g
