Question

find the greatest digit in place of * , if 36*4001 is div by 3​

Answer 1

Answer:

7

Step-by-step explanation:

To check the divisibility by 3 we sum all the digits on the number in this case we will take 3+6+4+1 = 14 and which isn't divisible by 3 so largest number we could replace by star is 7 which make the sum of digit to 21.

which is the greatest number between (1,9) which we can replace
