Find the values of the letters in the following and give reasons for the steps involved.

Here product of B and 6 must be same as ones place digit as B.
6 x 1 = 6, 6 x 2 = 12, 6 x 3 = 18, 6 x 4 = 24
On putting B = 4, we get the ones digit 4 and remaining two B’s value should be 44.
⇒ For 6 x 7 = 42 + 2 = 44
Hence, A = 7 and B = 4
