kritika gupta  (9 years ago)

Regular working hours in 4 weeks = (4 × 6 × 10) = 240 hours

Amount earned by working in these regular working hours
= 240 × 2.10 = Rs.504

Additional amount he earned = 525 - 504 = Rs.21

Hours he worked overtime = 21/4.2 = 210/42 = 5 hours

Total hours he worked = 240 + 5 = 245 hours

1 week----> 6 days
1 day------>10 hours
1 week ---->6 days* 10 hours = 60 hours
4 weeks----->60*4=240
1 hours he earn--------->2.1 rs
240 hours ---------->240*2.1=504
but he earn total amount ------- 525
extra amount =525-504=21
extra money per 1 hour ----->4,2
so 21 rs he take =214.2=5
then total hours are=240+5=245

In a week there are 6 working days.For 4 weeks 6*4=24 days. In a day 10 working hours, so 24*10=240 hours. 240*2.10=504 Rs. Remaining 21 Rs for overtime. 21/4.20=5. hence 240+5=245 days

one day working hour=10
in 1 week=6*10
=60 hours

1 hour sal=2.10
1 week sal=2.10*60
=126

4 week sal=126*4
=504 Rs

over time sal per hour=4.20

if he will work 5 hours ovre time=5*4.20
=21 Rs

total sal=21+504
=525 Rs

Then total hours required=240 (part time) +5 (over time)
=245 hours

Regular working hr = 4*6*10 =240 hrs
amount of regular work earned = 240*2.10 = rs. 504
extra = 525 - 504 = 21 , this extra amount he earned from overtime working
hence overtime work hr = 21/4.20 = 5 hrs.
so.. total hr he worked is = 240 +5 = 245 hr

k padmanabha Reddy  (7 years ago)

the man earns Rs 525 in 4 weeks
every week 6 working days =4*6=24days
every day 10 hours=24*10=240hours
every hour Rs2.10=240*2.10=504
the remining amount =525-504=21
Rs 21 he earns by overtime
the amount of over time is 4.20 per hour=21/4.20=5hours
the total hours=240+5=245
