6
hcf stands for "highest common factor"
factors of 12= 1,2,3,4,6,12
factors of 30=1,2,3,5,6,10,15,30
factors of 48= 1,2,3,4,6,8,12,16,24
6 is the highest overlapping factor so its is the "hcf".
180
first you need to add ten to 80 and then it gives you 90, but tom had 100 and gave ten to Ahmad resulting in 10 more. so that means 90 x 2 = 180
