**SHSAT Arithmetic Practice Problems :**

Here we are going to see some practice questions of the math topic "Arithmetic".

To find question from 1 to 6, please visit the page "SHSAT Arithmetic Practice".

**Question 7 :**

Which of the following is not less than 0.25 ?

(A) 2/9 (B) 3/14 (C) 16/64 (D) 19/80 (E) 2/9

**Solution :**

To find the number which is not less than 0.25, first let us convert the given decimal to fraction.

0.25 = 0.25 ⋅ (100/100)

= 25/100 = 1/4

By simplifying 16/64, we get 1/4.

Hence 16/64 is not less than 0.25.

**Question 8 : **

If the average of 5 consecutive odd numbers is 11 then the largest number is.

(A) 17 (B) 15 (C) 13 (D) 11 (E) 9

**Solution :**

The average of 5 consecutive odd numbers = 11

Let "x" be the odd number, four consecutive odd numbers are x + 2, x + 4, x + 6, x + 8

(x + x + 2 + x + 4 + x + 6 + x + 8)/5 = 11

(5x + 20) = 55

5x = 55 - 20

5x = 35

x = 7

The largest integer odd integer is x + 8

x + 8 = 15

Hence 15 is the largest odd integer.

**Question 9 :**

If r is an even integer, and s is an odd integer which of the following must be true ?

I r(r + s) is even

II s^{2} - r is odd

III 3r + 2s is odd

(A) None (B) I and II only (C) I and III only

(D) II and III only (E) I, II and III.

**Solution :**

**I r(r + s) is even :**

r = even, s = odd

r + s = even + odd = odd

r(r + s) = even (odd) = even (true)

**II s ^{2} - r is odd :**

odd^{2} - even = odd - even = odd (true)

**III 3r + 2s is odd :**

3(even) + 2(odd) = even + even = even (false)

Hence the answer is I and II.

**Question 10 :**

Points W, X, Y and Z all lie on the same line such that X lies between Y and Z, and W lies between X and Y, which of the following

I W is between X and Z.

II Y is between W and X.

III X is between W and Z.

(A) None (B) I only (C) II only

(D) III only (E) II and III

**Solution :**

**X lies between Y and Z.**

W lies between X and Y.

Hence the answer is option D.
