Answer» Answer: 75 Step-by-step explanation: LET the two digit NUMBER be 10x+y and no. obtained by interchanging the digital = 10y+x As per the first condition 10x+y= 6 (x+y)+3 4x-5y=3.. (i) As per the second condition 10y+x=4 (x+y)+9 -3x+6y=9.... (ii) Multiplying equation (i) by 3 and (ii) by 4 and ADDING them, we get 12x-15y=9 -12x+24y=36 ___________ 9y=45 y=455 Substitute y=5 in equation (i) 4x- 5X5=36 4x=28 x=7 So the numbers are 10x+y=10×7+5=75 HOPE THIS HELPS YOU!!
