Given:
VR Headset + VR Headset + VR
Headset = 30
VR Headset + 2 Controller + 2
Controller = 18
2 Controller – Camera Sensor = 2
Required:
Camera Sensor + VR Headset + 2
Controller = ?
Solution:
Equation 1:
VR Headset + VR Headset + VR
Headset = 30
3 VR Headset = 30
VR Headset = 30 / 3
VR Headset = 10
Equation 2:
VR Headset + 2 Controller + 2
Controller = 18
Put value of VR Headset in above
equation.
10 + 4 Controller = 18
4 Controller = 18 – 10
4 Controller = 8
Controller = 2
Equation 3:
2 Controller – Camera Sensor = 2
Put value of controller in above
equation.
2 (2) – Camera Sensor = 2
4 – Camera Sensor = 2
Camera Sensor = 4 – 2
Camera Sensor = 2
Now we have values of all unknown
variable & we can put these values in the final equation to find the value
of unknown.
Equation 4:
Camera Sensor + VR Headset + 2
Controller = ?
2 + 10 + 4 = Unknown
Hence Answer = 16
