Some equations have been solved on the basis of certain system.Find the correct answer for the equations on that basis.
if 72*19=23,13*48=35 and 16*43=18 then 39*22=?
option:
(1)31
(2)51
(3)21
(4)27

• 1).31
  ~72*19=23
  7*2+1*9=23
  ~13*48=35
  1*3+4*8=35
  ~16*43=18
  1*6+4*3=18
  ~39*22=?
  3*9+2*2=31

• Here in question it is given that
  72*19=23 which means (7*2+1*9)=23
  same for others
  13*48=35 which means (1*3+4*8)=35
  16*43=35 which means (1*6+4*3)=18
  so for
  39*22 which means (3*9+2*2)=31
  
  So, option 1). 31 will be the correct answer.
