Question 1 of 7
Assertion (A): If \(N\) leaves remainder 4 when divided by 7, then \(N+3\) is divisible by 7.
Reason (R): Adding a multiple of 7 to a number does not change its remainder on division by 7.
Select one option. Answers are shown after the test.
Question 2 of 7
Assertion (A): If two numbers leave remainders 5 and 3 when divided by 7, their sum leaves remainder 1.
Reason (R): Remainders must be added without reducing the result when their sum exceeds the divisor.
Select one option. Answers are shown after the test.
Question 3 of 7
Assertion (A): Reversing the digits of a multiple of 9 produces another multiple of 9.
Reason (R): Reversing the digits keeps every digit in the same place value.
Select one option. Answers are shown after the test.
Question 4 of 7
Assertion (A): A number leaving remainder 8 on division by 12 plus a number 4 short of a multiple of 12 is always a multiple of 8.
Reason (R): The sum has form \(12k+4\), and such numbers are not always multiples of 8; for example, \(k=2\) gives 28.
Select one option. Answers are shown after the test.
Question 5 of 7
Assertion (A): The assignment \(A=4,B=8,C=1\) satisfies \(AB+AB+AB=CAA\).
Reason (R): In a cryptarithm, the same letter may represent different digits in different places.
Select one option. Answers are shown after the test.
Question 6 of 7
Assertion (A): If a number is not divisible by 18, then it is not divisible by 9.
Reason (R): 27 is divisible by 9 but not by 18.
Select one option. Answers are shown after the test.
Question 7 of 7
Assertion (A): The sum of four consecutive integers can never be odd.
Reason (R): If the first integer is \(n\), the sum is \(4n+6=2(2n+3)\).
