A square field of size 72 — 72 is to be covered by rectangular tiles (with integral edges) with length to breadth ratio is 3 : 2. What is the difference between minimum and maximum number of tiles used? (A) 864 (B) 210 (C) 426 (D) 860 (E) None

max tiles = 72*72/2*3 = 864

minimum when dimension of tiles is 24X36 => 72*72/24*36 = 6

difference = 864 - 6 = 858

have been discussd b4

=> 864-6 => 858 ; none

length and breadth ka ration 3: 2 he toh min 3 x 2 hi hga..integers..3 x 2 min he , toh usse max no of tiles aayegi...so agar wahi no of tiles , dimensions hgi toh min no of tiles aayegi
so 3x 2 size ki 24 x 36 tiles
n 24 x 36 size ki min 3 x2 tiles

Please share the approach:-20 teams of 5 archers each compete in achery competition.An archerfinishing in kth place contributes k points to his team and there areno ties.The team that wins will be the one that has the leastscore.Given that 1st position team's score is not the same as anyother team,the number of winning scores possible is?1)2362)2373)2384)239ďťż
