When 40 is subtracted from 50% of a number, the result is 50% of 500. Find one-tenth of the number

• ans:-58
  
  50x/100=40+50*500/100
  x=580
  so,x/10=58

• ans. 2) 58
  x*(50/100)-40=500*(50/100)
  (x/2)-40=250
  x/2=250+40
  x/2=290
  x=580
  Now, x/10=580/10=>>58
  So, One-Tenth of x will be 42

• x*(50/100)-40=500*(50/100)
  (x/2)-40=250
  x/2=250-40
  x/2=210
  x=420
  Now, x/10=420/10=>>42
  So, One-Tenth of x will be 42.

• Assume like that unknown number is x,
  then,
  According to question,
  
  x*(50/100)-40=500*(50/100)
  (x/2)-40=250
  x/2=250+40=290
  x=580
  
  Now,
  x/10=580/10=58
  So, One-Tenth of x will be 58.
