Question

If A is twice as good as B can do the work 6 days then A can do the work in how many days?
whith explaination ​

Answer 1

from a mathematical sense, since A is twice as good as B, and B can do the work in 6 days, this means that A can complete the work twice as quick compared to B, so A will take 6 ÷ 2 days (or in other words, 3 days).

however, not from a mathematical perspective, it depends on how quickly A does the work. since A is twice as good as B, it does not necessarily mean that A finishes the work faster than B - it could just mean that A has a better quality of work than B. so, A could either finish the same work faster, slower or in the same amount of time as B.

hope this helps :)

Answer 2

if, a=2b

so, b complete it's work in 6 days then a will complete it's work in half of the days taken by b as a is twice good than b so answer and process can be written like this,

according to goodness = a = 2b

hence, a is twice good than b so it will take half of it,

so, 6÷2=3.

a will complete it's work in 3 days.

according to me.
