Four tests-Physics, Chemistry, Mathematics and Biology are to be conducted on four consecutive days, not necessarily in the same order. The Physics test is held before the test which is conducted after Biology. Chemistry is conducted exactly after two tests are held. Which is the last test held?

Four tests-Physics, Chemistry, Mathematics and Biology are to be conducted on four consecutive days, not necessarily in the same order. The Physics test is held before the test which is conducted after Biology. Chemistry is conducted exactly after two tests are held. Which is the last test held? Correct Answer    Mathematics

Chemistry is conducted exactly after two tests are held.

Day 1  
Day 2  
Day 3 Chemistry
Day 4  
 

The Physics test is held before the test which is conducted after Biology.

This means that Physics and Biology are not held on Day 4. Therefore, Mathematics is held on day 4.

Day 1  
Day 2  
Day 3 Chemistry
Day 4 Mathematics


Hence, option 3 is the correct answer.
