Question: A person stitches 10 shirt in a day. In how many days he can stitch 100 shirts?
Answer: Total Number of Days = ( Total Number of Shirts / Number of shirts in a day )
= ( 100 / 10 )
= 10 days.
Question: Similarly if we say, Person stitches 100 shirts in 10 days, how many shirts he can stitch in 1 day?
Answer : Number of Shirts in a day = (Total number of Shirts / Total number of days )
Number of Shirts in a day = ( 100 / 10 )
Number of Shirts in a day = 10 shirts in a day
Question: Now if some one asks if a person stitches 60 shirts in 5 days, in how many days he can stitch 108 shirts?
What will you do?
Answer :
Steps 1: Find number of shirts in a day as explained above.
Number of Shirts in a day = Total number of Shirts / Total number of days
Number of Shirts in a day = 60 / 5
Number of Shirts in a day = 12 shirts in a day
Step 2: Now total days to stitch 108 shirts are = Total number of shirts / Number of shirts in a day
= 108 / 12
= 9 days
Another Question: A person can repair 5 mobiles in a day. On a particular day he got 18 mobiles for repair. How many days he'll take to repair them.
Answer : Total Number of Days = Total Number of Mobiles / Number of mobiles in a day
= 18 / 5
= 3.6 days.
What is 0.6 days in this ?
Lets assume, person works for 8 hrs in a day, so 0.6 days will be some number of hours in a day.
0.6 means 60% of 8 hrs.
60/100*8 = 4.8 hrs
