Question

xyz×abba=xyzxyz find (a+b)=?​

Answer 1

Answer:

a + b = 1

Step-by-step explanation:

Given :

Xyz×abba=xyzxyz

RHS =  xyzxyz

Value of  xyzxyz can be written as

= 1000 (xyz) + xyz

= (1001)xyz

= xyz * 1001

LHS = Xyz×abba

Equating LHS & RHS

xyz * 1001 = Xyz×abba

=> abba = 1001

Hence

a = 1

b = 0

so sum of a + b = 1 + 0 = 1

=> a + b = 1
