A man was engaged on a job for 30 days on the condition that he would get a salary of rs. 1000 for the day he works, but he has to pay a fine of rs. 200 for each day of his absence. if he gets rs. 22,800 at the end, how many days was he absent for?

Complete step-by-step answer: Let he work for x days then he was absent for ( 30 − x) days Total amount paid = Rs. 216 Now according to question, 10 × x − 2 ( 30 − x) = 216 10 x − 60 + 2 x = 216 12 x = 276 x = 23 Number of working days = 23, therefore No of absent days = ( 30 − x) = 30 − 23 = 7 days

How are involuntary actions and reflex actions different from each other

Hint: Involuntary action is the collection of muscle activity that does not require planning. But, for one, it is regulated by the brain. While, on the other hand, in response to any stimuli that does not involve the brain is a reflex action which is quick and spontaneous movement. First we should know about the muscle movement to answer this.

How are involuntary action and reflex action different from each other

Involuntry acitons are not controlled by us they are independent process means therer is no stimulus involved in these actions but reflex action is also involumtary in nature but they involves stinulus measns funcitons or respond according to it.
