SSC CGL Math Previous Year Number System Question: 17
A six digit number is formed by repeating a three digit number; for example, 256, 256 or 678, 678 etc. Any number of this form is always exactly divisible by
Option A : 7 only
Option B : 11 only
Option C : 13 only
Option D : 1001
Show/Hide Answer Key
Option D : 4
The number (x y z x y z) can be written, after giving corresponding weightage of the places at which the digits occur, as
100000 x + 10000y + 1000z + 100x + 10y + z = 100100x + 10010y + 1001z = 1001 (100x + 10y + z)
Since 1001 is a factor, the number is divisible by 1001.
7 × 11 × 13 = 1001
As the number is divisible by 1001, it will also be divisible by all three namely, 7, 11 and 13 and not by only one of these because all three are factors of 1001.
So, the answer is 1001

The smallest number to be added to 1000, so that 45 divides the sum exactly, is
Option A : 35
Option B : 80
Option C : 20
Option D : 10
Show/Hide Answer Key
Option D : 4
1000 = (45 × 22) + 10
Then, 45 – 10 = 35 to be added.
So, the smallest number to be added to 1000 to make the sum exactly divisible by 45 is 35.
Advance Math Number System Question Asked in SSC CGL: 19
The divisor is 25 times the quotient and 5 times the remainder. If the quotient is 16, the dividend is
Option A : 6400
Option B : 6480
Option C : 400
Option D : 480
Show/Hide Answer Key
Option D : 4
Quotient = 16
Divisor = 25 × 16 = 400 and remainder = 80
Dividend = Divisor × quotient + Remainder
= 400 × 16 + 80
= 6400 + 80 = 6480
Previous Year Math Number System Question Paper SSC CGL: 20
When a number x is divided by a divisor it is seen that the divisor = 4 times the quotient = double the remainder. If the remainder is 80 then the value of x is
Option A : 6480
Option B : 9680
Option C : 8460
Option D : 4680
Show/Hide Answer Key
Option A: 6480
According to the question,
Divisor = 2 × remainder
= 2 × 80 = 160
Again, 4 × quotient = 160 \= 160 × 40 + 80 = 6480
