Ans : Divisibility by 4 :

⇒A number is divisible by 4,if the number formed by the last two digits are divisible by 4..

So,1540 the last two digits are 40....It is divisible by 4......

It is the divisiblity of 4....

Divisibility by 5 :

⇒A number is divisible by 5,if its ones digiti is '0' or '5'..

So,1540 the last digit is 0.....

It is the divisibility of 5....

__________________________

Divisibility by 11 :

⇒ A number is divisible by 11,if the difference between the sum of the digits at Odd places and the sum of the digit at even places is either 0 or divisible by 11.....

So,1540 (1+4 = 5)...5 is not a divisibility of 11......

It is not a divisibility of 11....
