a number when multiplied by 7/18 instead of 7/8 and got the result 770 less than the actual result , find the original number?

• If x is the number, then
  x*7/18 = x*7/8 -770
  x/18 = x/8 -110
  x/8-x/18 = 110
  5x/72 = 110
  x= 72*110/5= 72*22= 1584

• diff of result is 770
  diff of multipliers is 7/8-7/18= 35/72
  
  hence if no is x then 35x/72=770
  or x= 1584

• suppose no is x soo x7/8 -x7/18 ====770
  sooo x===1984

• let no be y
  7y/18=x-770
  7y/8=x
  7y/18=7y/8-770 solve it we get
  y=792
