Question
The unit’s digit of a two digit number ‘N’ is greater than 5 and is a multiple of ‘3’ while the ten’s digit is one more than the unit’s digit, then find the value of N^2
Options 6241
7396
5776
5041
Solution
The unit's digit of the two-digit number N is greater than 5 and is a multiple of 3. The only digits that satisfy this condition are 6 and 9. However, since the ten's digit is one more than the unit's digit, the only possible digit for the unit's place is 6 (because there is no digit 10). Therefore, the ten's digit is 7. So, the two-digit number N is 76.
Now, we need to find the square of N (i.e., N^2).
76^2 = 5776
So, the correct option is 5776.
