• B. 40 rubies
• C. 28 rubies and 9 emeralds
• D. None of these

Answer 1

The correct option is B 40 rubies

Option (b)

Number of emeralds which can be carried in total = 30. Value = 30 x 5 = 150 cr

Number of rubies which can be carried in total = 40. Value = 40 x 4 = 160 cr. Only rubies will give the maximum wealth
