Question

If 78K928L is divisible by 6, then which of the following can Q and R take ?

Answer 1

Q:

If 78K928L is divisible by 6, then which of the following can Q and R take ?

A) K=2 & L=3
B) K=1 & L=4
C) K=1 & L=2
D) K=3 & L=3

Answer:   B) K=1 & L=4 

Explanation:

As per divisibility rule a number is divisible by 6 means it should be divisible by 2 and 3
case 1 : the divisibility rule for 2 is the number should be end with even number 
in this case R =2 & R=4

case 2 : The divisibility rule for 3 is the sum of numbers should be divisible by 3
so if we take option (2) Q=1 & R=4 the sum is 39 
if we take option (3) Q=1 & R=2 the sum is 37
So Option (2) is correct 39 is divided by 3

Answer 2

If 78K928L is divisible by 6, then which of the following can Q and R take ?

A) K=2 & L=3
B) K=1 & L=4
C) K=1 & L=2
D) K=3 & L=3

Answer:   B) K=1 & L=4 

Explanation:

As per divisibility rule a number is divisible by 6 means it should be divisible by 2 and 3
case 1 : the divisibility rule for 2 is the number should be end with even number 
in this case R =2 & R=4

case 2 : The divisibility rule for 3 is the sum of numbers should be divisible by 3
so if we take option (2) Q=1 & R=4 the sum is 39 
if we take option (3) Q=1 & R=2 the sum is 37
So Option (2) is correct 39 is divided by
