Jisko answer aata ho wahi de kripya kar ke warna na de pls ​

Answer 1

Answer:

B= 0, 3, 6, 9

Step-by-step explanation:

If a number leaves remainder 0 when divided by 3 , the sum of the digits will leave remainder 0 also.

for this, 4+2+5+2+7+4+6+B =30+B leaves remainder 0 too.

here the remainder is (30+B) % 3 = B     (% is the sign of remainder)

Now B will be divisible by 3.

B =3×0=0

  =3×1= 3

  =3×2= 6

  =3×3= 9

  =3×4 = 12 (not acceptable)

B= 0, 3, 6, 9

Answer 2
