Find the values of the letters and give reasons for the steps involved. `AB xx 5 = CAB`

Text Solution

Verified by Experts

In given problem, if B×5 has to end with B, then B has to be either `0` or` 5`,
because only `0` or `5`, when multiplied by `5`, will give the same number.
If B=`5`, then there will be a carry-over,
thus, it will not give next product as CA
hence, B=0.
Also, A×`5` ends with A, so A=`5`.
and `5×5=25`
∴ C=`2`
Hence, A=`5`,B=`0` and C=`2`.
