In school there some bicycles and 4 wheeler wagons. On Tuesday there are 58 wheels in the campus. How many bicycles are there ?
Option
a) 7
b) 8
c) 9
d) 6
Read Solution (Total 17)
-
- May be it's a dummy que as both 7 and 9 are suitable for the given condition.
- 10 years agoHelpfull: Yes(12) No(0)
- let no of bicycles(2wheels) be B
and no of wagons(4wheels) be W
total no of wheels = 2B+4W =58
B+2W=29------->this shows B must be an odd number.
therefore from the given options ans is 9 - 10 years agoHelpfull: Yes(2) No(1)

- either 7 or 11(a/c).
Bcz (58-(7*2))/4=11,
similarly for 9 is 10 four wheelers.
where as for 8 and 6 it is in fractions. so nither b nor c - 10 years agoHelpfull: Yes(1) No(0)
- 7/9 can be the ans
- 10 years agoHelpfull: Yes(1) No(0)
- either 7 or 9.....

- ans can be both 7 or 9.
let the no of bicycles be x and no of 4wheeler wagons be y.so 2x+4y=58. on substituting the values 7 and 9 in place of x we get, 2*7+4*11=58 and 2*9+4*10=58 hence both the options 7 and 9 are valid - 10 years agoHelpfull: Yes(1) No(0)
- as per options ans may be 7 or 9 both are possible.
- 10 years agoHelpfull: Yes(1) No(0)
- 7 bicycles are there
- 10 years agoHelpfull: Yes(0) No(1)
- 7
because 7*2=14 and 58-14=44/4=11
7 bycyles and 11 four wheel vagons - 10 years agoHelpfull: Yes(0) No(0)
- from ans we can find
9*2=18
58-18=40
divisible by 4
ans = 9
- 10 years agoHelpfull: Yes(0) No(0)
- a)7. coz....7*2=14....
58-14=44
44/4=11(absolutely divisible).
actually:4 wheelers shld be seperated. - 10 years agoHelpfull: Yes(0) No(1)
- it will be 48/4=12 four wheel and 58-48=10 10/2=5 bycyles
- 10 years agoHelpfull: Yes(0) No(0)
- Ans. 9 Bicycles
because 9*2=18 and 58-18=40/4=10
9 bicyles and 10 four wheel Wagons - 10 years agoHelpfull: Yes(0) No(0)
- 7 or 9
and data insufficient
- 10 years agoHelpfull: Yes(0) No(0)
- let no of bicycles be x and wagons be y
then 4y+2x = 58
only 7 and 9 satisfies this - 10 years agoHelpfull: Yes(0) No(0)
- answer is d)6
as bicycles are 2 wheelers
and assume 4x for 4 wheeler wagons
so
equation will be
(2wheelers)+4x=58
now value for 2 wheeler i.e cycle select from option
let us assume first a)7
so,
7+4x=58
4x=58-7=51
x=51/7 as it is not divisible by seven so it is incorrect option
same is for option b and c
now assume option (d)6
(2wheeler)+4x=58
6+4x=58
4x=52
x=13
so it is divisible so answer is (d). - 10 years agoHelpfull: Yes(0) No(2)
