Question 1083807: in a survey 1/3 children like only mango and 25 donot like mango at all also 2/5 children like orange but 16 like none of them. then show above data in venn-diagram and find number of children who like both fruit Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! This is 2 interlocking circles giving you
3 distinct regions:
(1) Only like mango
(2) Like both mango and orange
(3) Only like orange
-------------------------------
They tell you that everything outside these
2 circles is children ( like none of them )
--------------------------------------------
Let = the total number of children
Area (1) Only like mango =
-------------------------------------- do not like mango.
Let = (3) Only like orange
--------------------------------------- = like orange = area (2) Like both mango and orange
----------------------------------------------------
I have specified the 3 areas and also everything outside ( children )
so, now I can say:
--------------------
(2) Like both mango and orange =
So 15 children like both fruit
----------------------------
check the answer: = area (1)
------------------------------ = area (2)
------------------------------- = area (3)
and = children who like neither fruit
--------------------------------------
OK
