Question 1207359
<br>
Straightforward calculations that you should be able to do yourself....<br>
Rs 12000 for the month from his work at the laundry shop.<br>
Then, for his work as a cashier....
Rs 150 per hour, times 8 for each 8-hour shift, so Rs 1200 per shift.
Rs 1200 per shift, times 5 shifts per week, so Rs 6000 per week.<br>
But we don't now how much he makes from his work as a cashier in a month, because you have not defined what a "month" is.  Is it 4 weeks? Is it 30 days? Is it something else?<br>
If you want us to work the whole problem for you, you need to define the problem clearly.<br>
But this is a problem that you shouldn't need us to work for you....<br>
