Answer: There are 35 bicycles, 33 tricycles and 50 tandem bicycles.
Step-by-step explanation:
Since we have given that
Number of seats = 135
Number of front handle bars = 118
Number of wheels = 269
Since there are 118 front handle bars.
And we know that each bicycle has 1 front handle bars.
So, total number of bicycles = 118
Now, each bicycle has 2 wheels
So, Number of wheels should be
But here we have 269 wheels , it means it has tricycle which has 3 wheels.
So, Remaining wheels would be
It means 33 bicycles has 3 wheels .
So, Number of tricycles = 33
So, Number of bicycles should be now
Each bicycle has 1 seat
So, number of seats should be 85
But we have 135 seats,
So, remaining seats should be of tandem bicycle.
So, Number of bicycles now becomes
85-50 = 35
Hence, there are 35 bicycles, 33 tricycles and 50 tandem bicycles.
