Question 1112673
<br>
The total pay if he worked all 30 days at Rs 120 per day would be Rs 3600.<br>
On each day of work he misses, he does not get the Rs 120 for that day, AND he loses Rs 30 as a penalty.  So for each day he misses work, his total pay goes down by Rs 150.<br>
His pay for the 30 days was Rs 2700, which is Rs 900 less than he would have made working all 30 days.<br>
So the number of days of work he missed was 900/150 = 6.<br>
ANSWER: He missed work 6 days<br>
