• total work:30days
  25 rupees per day
  7.50 rupees cut on will not attend work per day
  suppose,
  he will attend 20days of the work ,
  he engaged for-20*25=500,
  he will not attend work for 10days,then 10*7.50=75,
  finally 500-75=425.

• A )10 days
  Solution--
  Let he work for x days
  So,he is absent for (30-x)days
  So, total amount that he got is x*25+(30-x)*7.5=425
  Solving,x=20
  So, 30-x=10

• Total work day-30 days
  If he attends 17 days

• Total working days are 30
  Amount for one day if he works = Rs.25
  If he has worked for 20 days = 20 * 25 = Rs.500
  
  Amount deducted if he was absent = Rs.7.50
  If he was absent for 10 days = 10* 7.50 = Rs. 75
  The amount he received = Rs.500 - Rs. 75= Rs.425

  If he works for x days then: 25x - 7.5(30-x) = 425 -----> (25+7.5)x = 425+30*7.5 ----> x=20

• A. 10
  
  If he works for x days then: 25x - 7.5(30-x) = 425 -----> (25+7.5)x = 425+30*7.5 ----> x=20
  There fore number of days he was absent would be (30-20)days =10 days
  
  Sorry for the previous answer (E. None is wrong)...
