Solution

✅ Correct Option: 3

When finding remainders for division by 3, the remainder of any number divided by 3 equals the remainder when the sum of its digits is divided by 3.


For 672: 6+7+2=156+7+2 = 15, which gives remainder 00 when divided by 3

For 541: 5+4+1=105+4+1 = 10, which gives remainder 11 when divided by 3

For 383: 3+8+3=143+8+3 = 14, which gives remainder 22 when divided by 3

For 295: 2+9+5=162+9+5 = 16, which gives remainder 11 when divided by 3

For 101: 1+0+1=21+0+1 = 2, which gives remainder 22 when divided by 3

For 86: 8+6=148+6 = 14, which gives remainder 22 when divided by 3


The sum of all remainders:

0+1+2+1+2+2=80 + 1 + 2 + 1 + 2 + 2 = 8


Finding the remainder when 8 is divided by 3:

8=3(2)+28 = 3(2) + 2

Therefore, the remainder is 22.
