 If it is possible to make a number which is perfect square of a twodigit odd number with the second, the sixth and ninth digits of the number 187642539. which of the following is the digit in the unit’s place of that twodigit odd number?

View Hint View Answer Discuss in Forum
The specified digits are 8, 2 and 9. Now, we know a perfect square number does not have 8 and 2 at unit’s place. Therefore, we can make only two threedigit numbers from it, i.e., 829 and 289. Among these two numbers, 289 is a perfect square number, i.e., square of 17. Thus, unit’s digit is 7 and ten’s digit is 1.

Let us assume the number of boys in school be B.
Then number of girls in school = 2B
According to question,
B + 2B = 180
3B = 180
B = 180/3 = 60
Number of boys = 60
Number of girls = 120
Rupesh (a boy) ranked 34^{th} from top and 18 girls are ahead of Rupesh.Correct Option: B
