Question

Find the circumcenter of the triangle whose vertices are A(1,3)B(-3,5)c(5,-1)

Answer 1

Answer : C.

STEP BY STEP

If A takes x days to do a work then B takes 2x days to do the same work.

--> 1/x+1/2x = 1/18

--> 3/2x = 1/18

--> x = 27 days.

Hence, A alone can finish the work in 27 days.
