Q:

# How many such digits are there in the number 7346285 which are as far away from the beginning of the number, as they will be when arranged in ascending order within the number?

 A) None B) one C) Two D) Three

Explanation:

$\inline \fn_jvn \begin{matrix} Given\; Number & : &7\; \underline{}3\; \underline{}4\; 6\; 2\; 8\; 5 \\ Ascending \; Order& : & 2\; \underline{}3\; \underline{}4\; 5\; 6\; 7\; 8 \end{matrix}$

Q:

Q:

If it is possible to form a number with the second, the fifth and the eighth digits of the number 31549786, which is the perfect square of a two - digit even number, which of the following will be the second digit of that even number ?

 A) 1 B) 4 C) 6 D) None of these

Explanation:

The 2nd, 5th and 8th digits of the number 31549786 are 1, 9 and 6 respectively.

The perfect square of a two - digit even number, formed using the digits 1, 9 and 6 is 196. And, $\inline 196 = 14^{2}$

So, the required even number is 14. Clearly, its second digit is 4.

Q:

If the digits in the number 25673948 are arranged in ascending order from left to right, what will be the sum of the digits which are fourth from the right and third from the left in the new arrangement?

 A) 10 B) 9 C) 8 D) 6

Explanation:

Given Number :      2 5 6 7 3 9 4 8

Ascending order :  2 3 4 5 6 7 8 9

Specified letters are 6 and 4 respectively.

$\inline \therefore$ required sum = (4 + 6 =) 10

Q:

382  473  568  728  847  629

If 382 is written as 238, 473 as 347 and so on, then which of the following two numbers will have least difference between them?

 A) 473 & 382 B) 629 & 728 C) 629 & 847 D) 728 & 847

Explanation:

The given numbers are :

382  473  568  728  847  629

When changes are made as given in the question, numbers become as follows :

238  347  856  872  784  962

Again now, find out the difference between the numbers given in options as given below:

(1) 473 - 382  => 347 - 238 = 109

(2) 629 - 728  => 962 - 872 = 90

(3) 629 - 847  => 962 - 784 = 178

(4) 728 - 847  => 872 - 784 = 88
