Re: a a tricky one
If for every 3 wrappers I get 1 soap free ( with wrapper of course )
How many soaps do I need to buy to get 20 soaps Easy one..... for every 3 soaps we get 1 more soap 3=4(3+1) 6=8(6+2) 9=12(9+3) 12=16(12=4) 15=20(15+5) so to get 20 soaps we have to buy 15 soaps...... I think I am correct.....  correct me if i am wrong!!!!!!!!!!!

Re: a a tricky one
251/11 = 22 soaps(22 scraps) and 9 scraps
22 scraps leaves 2 more soaps(22+2(2 scraps)) that 2 scraps will be added with 9 scraps to get 1 more soap(22+2+1(1scrap)) So final answer is 25 soaps and 1 scrap remaining......
