Efficiency and ratio | Part 2

Ratio of efficiency of P and Q is 3 : 4. Find the ratio of number of days they will take to complete the work

A takes 16 days to finish a job alone, while B takes 8 days to finish the same-job. What is the ratio of their efficiency and who is less efficient.

The ratio of working efficiency of A and B is 5:3 and the ratio of efficiency of B and C is 5:8. Who is the most efficient?

The efficiency of otto cycle for petrol engine is 50% and the adiabatic constant is 1.4. calculate the compression ratio.
