In a party , where there were 200 quests, 60% had veg food, 50% had non veg, 30% of guest had both veg and non veg, how many % did not dine at the party?
a-30
b-35
c-40
d-45
Read Solution (Total 17)
-
- Total guests =200
Dine members=(veg+nonveg - both)%
(60+50- 30)%
=80%
Not Dine members=100%- 80%
=20% of 200
=40 members - 8 years agoHelpfull: Yes(37) No(1)
- Option: C
using ven diagram i solved this
Total 200 people of this 60% -Veg food = 120
Total 200 people of this 50% - non- Veg food =100
30% both veg and non veg=60
veg only=60
only non veg=40
both=60
therefore people didnt dine=> 60+60+40+x=200
=>x=40 - 8 years agoHelpfull: Yes(15) No(2)
- Veg 60% = 120 , Non Veg 50% = 100, Common 30% = 60
Total people who ate = 120 +100 -60=160
Thus people who didn't eat = 200 -160 = 40
Ans: C - 8 years agoHelpfull: Yes(10) No(1)
- why not 20...It ask about %
- 8 years agoHelpfull: Yes(5) No(0)
- let people not took part=x;
a U b= a+ b-a intersactin b;
200-x=120+100- 60;
x=40 ie 20% - 8 years agoHelpfull: Yes(2) No(0)
- c 120+100+60-200=80 which is opt c
- 8 years agoHelpfull: Yes(1) No(6)
- from 200,60% veg means 120
50% non veg means 100
30% both means 60
so % did not dine=200-120-100+60=40 - 8 years agoHelpfull: Yes(1) No(0)
- P(AUB) = P(A) + P(B) -P(A^B) = 60% + 50% - 30% = 80%
So, 80% of 200 = 160
therefore, 200 - 160 = 40.
40 members. - 7 years agoHelpfull: Yes(1) No(0)
- 60*200/100+50*200/100-30*200/100=160 and remaining 40 members
- 8 years agoHelpfull: Yes(0) No(0)
- Total guests =200
Dine members=(veg+nonveg - both)%
(60+50- 30)%
=80%
Not Dine members=100%- 80%
=20% of 200
=40 members - 8 years agoHelpfull: Yes(0) No(0)
- C. 40
as,
Veg = 60% ie 120
Non-Veg = 50% ie 100
Both : Veg U nVeg = 30 % ie 60
200 = dont't eat + veg + nVeg - Veg U nVeg
200 = X + 120 + 100 -60
X = 40 - 8 years agoHelpfull: Yes(0) No(0)
- n(Nveg) = 50%(200) = 100
n(veg)=30%(200) = 120
n(both)=60%(200)=60
n(Nveg U veg) = n(Nveg)+n(veg)- n(Nveg - veg))
=120+100-60= 160
=> 200 - 160 = 40 - 7 years agoHelpfull: Yes(0) No(0)
- answer is c-40
solution is:-
veg=60%, non-veg=50%, veg and non-veg=30%
so, veg or non-veg=60%+50%-30%=80%
so, who don't eat either veg or non-veg i.e. who didn't eat any food= 100%-80%=20%
means, 20% of 200=40 quests didn't eat any food. - 7 years agoHelpfull: Yes(0) No(0)
- P(A U B) =P(A) + P(B) - P(A n B)
P(A)=60/100
P(B)=50/100
P(A n B)=30/100
Therefore, P(A U B)=60/100 + 50/100 - 30/100
P(A U B)=80/100
Required is P (A' U B')=1- P(A U B )
P(A' U B')=20/100
Hence , no of people who didnot dine is 20/100*200=40 - 7 years agoHelpfull: Yes(0) No(0)
- answer is 20%

- 200 quest= 40 100*200=80 quest veg food
200 quest= 50100*200= 100 non veg food
200 quest = 70100*200 = 140 both
dine = (80+100-140) = 40 member not dine - 5 years agoHelpfull: Yes(0) No(0)
