Change the position of two digits in the number 527253 so that the number formed will become divisible by 11.
Dear Student,
Solution) Divisibility rule of 11 : The sum of the even digits is subtracted from the sum of the odd digits. The result is either 0 or divisible by 11.
Here,
sum of even digits = 2 + 2 = 4 and
sum of odd digits = 5 + 7 + 5 + 3 = 20.
Now, on subtracting, we get,
20 - 4 = 16 which is not divisible by 11.
Regards!
