Question 1. On Dividing A Certain Number By 234, We Get 43 As Remainder. If The Same Number Is Divided By thirteen, What Will Be The Remainder?

Answer :

assume that on dividing the given range by 234,

we get quotient=x and the rest= 43

then, quantity= 234*x+43----->(1).

=> (thirteen*18x)+(thirteen*three)+4

=> thirteen*(18x+3)+four.

So, the wide variety while divided through 13 gives remainder=four.

Question 2. Find The Remainder When 3^27 Is Divided By 5?

Answer :

three^27= ((3^4)^6) * (3^three) = (eighty one^6) * 27 then unit digit of (81^6) is 1 so on multiplying with 27, unit digit inside the end result might be 7. Now, 7 whilst divided through five gives 2 as the rest.

Question 4. 597**6 Is Divisible By Both 3 And eleven. The Nonzero Digits In The Hundred’s And Ten’s Places Are Respectively?

Answer :

Let the given wide variety be 597xy6.

Then (five+9+7+x+y+6)=(27+x+y) have to be divisible by way of three

And, (6+x+9)(y+7+5)=(xy+3) must be both zero or divisible by using 11. Xy+three=zero

=> y=x+3 27+x+y)

=>(27+x+x+3)

=>(30+2x)

=> x = 3 and y = 6.
