If the combined volume is 12 cubic units, then milk in the resulting solution = (4/5)*3 + (3/4)*4 + (5/7)*5 = 314/35
So, the required ratio = (314/35)/(12-(314/35)) = 157/53

If n is odd it can be expressed as 2k+1 for any integer k.zagcollins wrote:If n is a positive integer and r is the remainder when n^2-1 is divided by 8, what is the value of r?
1)n is odd
2)n is not divisible by 8
So, n^2-1 = (2k+1)^2-1 =4k^2+4k=4k(k+1)=8m (where m is another integer)=> r=0 for all odd n.

Ankur's reasoning is perfect.
Basically, what B says is triple-trailer trucks were not themselves the reason for the low number of accidents, but rather the reason was strong experience of the drivers of these trucks. So, the whole point of increasing more such trucks becomes irrelevant!
