A 4 Digit Number 8a43 Is Added To Another 4 Digit Number 3121 To Give A 5 Digit Number 11b64, Which Is Divisible By 11, Then (a+b)=? |

Answer» a+1=b => ba=1. => (4+b+1)(6+1)=0 => b2=0 => b=2. so, a=1 =>(a+b)= 3. a+1=b => ba=1. and 11b64 is divisible by 11 => (4+b+1)(6+1)=0 => b2=0 => b=2. so, a=1 =>(a+b)= 3. |
