Question. The given grap shows Raju’s pulse rate. Which of the following is the most probable condition during which pulse rate was recorded? 

(a) Raju ran for 10 minutes, rested for 10 minutes and ran again
(b) Raju did warm up exercise for 10 minutes, rested for 20 minutes and ran again
(c) Raju slept for 1 hour, walked for 1 hour and slept again
(d) Raju walked for 1 hour, rested for half an hour and walked again
Answer: B
Explanation: From the given graph, it is clear that initially for sometime, Raju’s pulse rate was constant but thereafter it increased for sometime and then decreased. Time during which the pulse rate decreased is more than the time during which pulse rate increased. Finally his pulse rate increased again. This can be explained as follows.
In the beginning Raju was resting so his pulse rate was constant but when he started warm up exercise his pulse rate increased. His pulse rate dropped when he rested after warm up exercise and finally when he started running, his pulse rate again increased.
