Number system

The number system is one of the most important sections included in the aptitude section, because the topic is generally as difficult as the students find it to be. There are many systems for representing numbers, but the most prevalent system in these systems is the number system, also known as the Dashmic system / Hindu-Arabic numbering system. Under this system, we use signs (0, 1, 2, 3, 4, 5, 6, 7, 8 and 9) called digits to denote a number. We use these ten digits to denote a number. Also, the Competition Exam covers 3 to 4 questions related to the marks system under the Aptitude section. Here you can practice more by solving important quiz based on the marks system with the help of the given blogs.

Answer : 1
11

Explanation :
Let the number be 10x + y
After interchanging the digits,
the number obtained = 10y + x
According to the question,
Resulting number
= 10x + y + 10y + x
= 11x + 11y
= 11 (x + y)
which is exactly divisible by 11.

If two numbers are each divided by the same divisor, the remainders are respectively 3 and 4. If the sum of the two numbers be divided by the same divisor, the remainder is 2. The divisor is

Answer : 4
1036

Explanation :
Let the quotient be Q and the remainder be R. Then
Divisor = 7 Q = 3 R
∴ Divisor = 7 Q = 7 × 12 = 84
Dividend = Divisor × Quotient + Remainder = 84 × 12 + 28 = 1008 + 28 = 1036
