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
![118\times 2\\\\=236\ wheels](https://tex.z-dn.net/?f=118%5Ctimes%202%5C%5C%5C%5C%3D236%5C%20wheels)
But here we have 269 wheels , it means it has tricycle which has 3 wheels.
So, Remaining wheels would be
![269-236\\\\=33\ wheels](https://tex.z-dn.net/?f=269-236%5C%5C%5C%5C%3D33%5C%20wheels)
It means 33 bicycles has 3 wheels .
So, Number of tricycles = 33
So, Number of bicycles should be now
![118-33=85](https://tex.z-dn.net/?f=118-33%3D85)
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.
![135-85=50](https://tex.z-dn.net/?f=135-85%3D50)
So, Number of bicycles now becomes
85-50 = 35
Hence, there are 35 bicycles, 33 tricycles and 50 tandem bicycles.
