69
B.
78
C.
96
D.
Cannot be determined
E.
None of these

• two digit no. is xy
  sum is
  x+y=15
  diffrence is
  x-y=3
  on solving these two eq we have x=9 and y=6

• let first no is x
  second number is y
  so x+y=15
  x-y=3
  solve this we get 2x=18
  x=9
  y=6
  two digit number is 96 option c.

• x+y=15,x-y=3
  2x=18,x=9 ,2y=12,y=6
  The two digit number xy=96,option isC

• x+y=15
  x-y=3
  on adding both eqn. we get x=9
  now putting x value in any one of d given eqn. we get y=6 an d hence no. is 96

• 9+6=15
  9-6=3
  ans:c)96
