Top 100+ Basic Arithmetic Interview Questions And Answers
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.
