+12 The mean of 5 numbers is 11. The numbers are in the ratio 1:1:2:3:4 Find the biggest number
+194
Explanation:
If the mean is 11 and there are 5 numbers then their sum is 5×11=55
We have the ratio of parts being a:b:c:d:e→1:2:3:4:5 so the total count of parts is 1+2+3+4+5=15
+36915 5 numbers mean = 11 5 x11= 55
there are 1+1+2+3+4 = 11 parts each part = 5
the largest number has 4 parts of the 55 55/11 x 4 = 20 = biggest number
