Options:
320
322
324
326
Z is a two digit number where, the unit's place digit is 3.
If the sum of the digits is equal to 1/7 of Z then, find the value of Z.
73
43

X is a two digit number.
If the digits are interchanged and the new number is added to X then, the result is divisible by which number?
10
11
12
13
Find the ratio of two numbers if their sum is 40 and their difference is 4.
18:11
21:17
11:9
22:9
x + y = 40
x - y = 4
so, x = 22
and y = 18
If the difference and the sum of the two numbers is 13 and 25 respectively. Then, find the smaller number.
5
6
7
8
x - y = 13
x + y = 25
so, x = 19 and y = 6
If the sum of three numbers is 264.
Then, what is the second number if the first number is twice the second and the third number is 1/3 of the first.
72
84
56
49
If the difference between a two digit number and the number obtained by interchanging its digits is 36.
Then, what is the difference between the two digits?
3
4
None of these
N represents an interger number consisting of 3 digits.
If the sum of the digits is 10 and the middle digit is equal to the sum of the other two digits.
And if 99 is added to N then, the digits are reversed.
Find N.

If M and N represents two natural numbers and if their product is 17 then, what is the value of the sum of their reciprocal of their squares.
290/287
290/289
289/290
287/290
M.N = 17
or, M = 1 and N = 17.
So, 1/M2 + 1/N2 = 290/289
If N is an interger and the sum of N and its reciprocal is 34/8. Then, find the product of N and its square root?
