• The liver is situated on the right side of the stomach.
• The main function of the liver is to produce bile pigment.
• Ammonia and urea are produced in the liver.

1) Lalit scored 72 marks in 100-mark test.

Shubham scored 8 marks more than Lalit but 6 marks less than Sunil.

Thus, Shubham’s marks = 72 + 8 = 80

Sunil’s marks = 80 + 6 = 86

Therefore, Lalit < Shubham < Sunil.

2) Ravi scored 6 marks less than Daniel, and 7 marks more than Sunil.

Ravi’s marks = Sunil’s marks + 7

Daniel’s marks = Ravi’s marks + 6

Thus, Sunil < Ravi < Daniel.

Now, we have the following order:

Lalit < Shubham < Sunil < Ravi < Daniel

Second lowest = second in ascending order.
