Question -:
What number can be divided into 2 and 9 equal groups without a remainder?
A. 36
B. 63
C. 99
D. 117
Explanation -:
Divisibility rule of 2
- If a number is even or a number whose last digit is an even number i.e. 2,4,6,8and 0 it is always divisible by 2.
Only 36 is even.
Divisibility rule of 9
- If the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.
a) 3+6 = 9
b) 6+3 = 9
c) 9+9 = 18
d) 1+1+7 = 9
Hence, the 36 is the correct answer.
