Question

give with out actually dividing, the remainder of 730/3​

Answer 1

Hey

The remainder of 730/3 is 1

Explanation :-

Divisiblity for 3 is when we add all the digits it should be a multiple of 3 so when we add 730 it becomes 10 and 9 is a multiple of 3

10 - 9 = 1

Hence the remainder is 1

Answer 2

hence,the sum of digits=7+3+0=10

which is not the multiple of 3

so ,nearest no.10 which is the multiple is 9so,

We will subtract from the no.

730-1=729

the remainder is 1
