Answer 1

Answer:

2

Step-by-step explanation:

we know to find weather 3 is divisible BY ANY NUMBER WE ADD THE NUMBERS IN THE PROBLEM

=>6+3+4+2+*+1 MUST BE EQUAL TO 18

BECAUSE ON ADD NUMBERS WITHOUT '*'WE GET 16 THEREFORE IT IS NOT DIVISIBLE BY 3 BUT TO MAKE IT DIVISIBLE BY 3

WE HAVE TO ADD IT BY 2 TO MAKE THE SUM OF NUMBERS EQUAL TO 18

[THEREFORE 18 IS DIVISIBLE BY 3]

=> THE LEAST VALUE GIVEN TO '*' IN NUMBER 6342*1

=2

Answer 2

Answer:

here to make the given number divisible by 3 it's sum should be divisible by 3

here 6+3+4+2+1= 16

if 2 is added then it will be exactly divisible by 3

so least value = 2
