Yes! Now I am in 10thNumber Theory Level 2
In a school two exams are taken every year. First of 30 marks and second of 70 marks. In the first exam you require 10 marks to pass and in the second exam 23 marks. To be promoted you have to pass in both the exams. The combined marks are announced. Without knowing the separate marks at what minimum marks can I be sure that I have been promoted?
