Question

One fine morning, Rizwan was up early at 7 AM. He looked outside the window. It was snowing heavily. He craved some ginger ale for breakfast. He headed to the fridge for some, but instead, he found orange juice cans of 2 colours, brown and green. He took out 2 cans of the same height but the brown can was thicker than the green one.

The brown can’s quantity was supposed to last for 6 hours and the smaller green can was supposed to last for 2 hours less. He took them out and kept them on the table. After a while, he found that the big brown can was twice longer than the smaller green one and it’s colour had changed to blue. He remembered that the big brown can had changed in colour due to a change in temperature, but he couldn’t figure out how the length increased. So, he started an investigation.

Find out, for how long in hours was Rizwan outside?
