Mr. T has a wrong weighing pan. One arm is lengthier thanother.1 kilogram on left balances 8 melons on right.1 kilogram on rightbalances 2 melons on left. If all melons are equal in weight, what is theweight of a single melon
Read Solution (Total 7)
-
- Ans:- 200grm
Solution:-
R L
8m 1kg
1kg 2m
total melons in Right and Left = 10melons
total kilogram in Right and Left = 2kg
for balance
10melons = 2kg
5melons = 1kg
So that weight of 1 melons = 1000/5 = 200grm

- 1kg + Extra-Weight = 8 melons ---(1)
and
2 melons + Extra-Weight = 1kg
can also be written as
1kg - Extra-Weight = 2 melons ---(2)
solving (1) and (2)
2kg = 10 melons => 1 melon 200gms

- ans is rs250 each melon bcoz
left:right
1000:8x=2x:1000
which gives x=250
where x is wt of 1 melon - 10 years agoHelpfull: Yes(5) No(4)
- let the left pan weight be x ,right pan weight be y,melon weight be z
then, x+1=y+8z,
x+2z=y+1
hence 1-2z=8z-1
10z=2
z= 0.2 kg =200 grams - 10 years agoHelpfull: Yes(4) No(0)
- as arms of weiging pan are not equal, they should also be considerd....
bczz of which answer cant be determined - 10 years agoHelpfull: Yes(2) No(0)
- 200 gm
8mellons =1600 gm
2 mellons =400 gm
here
1000 gm + 600gm= 1600 gm(8 mellons) and 600gm + 400gm(2 mellons) = 1kg - 10 years agoHelpfull: Yes(2) No(1)
- 8x=1000g+2x
8x-2x=1000g
6x=1000g
So x=1000/6g
X=166.67g - 9 years agoHelpfull: Yes(0) No(0)
