    Answer:

    A=5 and B=2

    Step-by-step explanation:

    BA×B3=57A

    as B is in 10

    s place

    ⇒(10×B+A)×(10B+3)=(57×10)+A

    ⇒100B

    2

    +10(A×B)+30B+3A=570+A

    ⇒100B

    2

    +10(A×B)+30B+2A=570

    ⇒2A=570−100B

    2

    −10(A×B)−30B

    ⇒10/2A as 10 divides RHS

    ⇒A=5

    or A=0

    for A=0, 100B

    2

    +30B=570

    ⇒10B

    2

    +3B=50+7

    no B satisfies this as

    3B=7

    for A=5,100B

    2

    +80B+10=570

    ⇒10B

    2

    +8B=56

    ⇒5B

    2

    +4B=28=20+8

    ⇒B=2

    ∴B=2,A=5
