Direction: The line chart given below shows number of labourers (men and women) working in six different years. Study the data carefully and answer the following questions. 

The total number of Men working in 2012 and 2013 together is what per cent of the total number of labourers (Men + Women) working in 2014? 

In △PQR, ∠P = 90°. S and T are the mid points of sides PR and PQ, respectively. What is the value of RQ²/(QS²+ RT²)?

A and B start moving from places X and Y and Y to X, respectively, at the same time on the same day. After crossing each other, A and B take $$5{4\over 9}$$ hours and 9 hours, respectively, to reach their respective destinations. If the speed of A is 33 km/h, then the speed (in km/h) of B is:
