Answer:

35 and 78 is answer

Answer 2

Answer:

A = 7, B = 5

we have A8 × 3B = 2730....ie when we multiply 8 and B we get a number ending with zero ( since 2730 ends with 0).

so B = 5. (as 8 × 5 = 40 which ends with 0)

so putting B as 5,

A8 × 35 = 2730

A8 = 2730/35 = 78

A8 = 78

so A = 7.

hence B=5 and A = 7
