## Basic Maths: Test 4

Congratulations - you have completed Basic Maths: Test 4. You scored %%SCORE%% out of %%TOTAL%%. You correct answer percentage: %%PERCENTAGE%% . Your performance has been rated as %%RATING%%
 Question 1
54.5% of 600 + 30.5% of 1800 = (p)2+200
 A +36 or -36 B +26 or -26 C –81 or +81 D none
Question 1 Explanation:
$\displaystyle \begin{array}{l}\frac{54.5\times 600}{100}+\frac{30.5\times 1800}{100}={{p}^{2}}+200\\\Rightarrow 327+549={{p}^{2}}+200\\\Rightarrow 876={{p}^{2}}+200\\\Rightarrow {{p}^{2}}=876-200=676\\Therefore\,\,p=\sqrt{676}=\pm 26\end{array}$
 Question 2
$\displaystyle \sqrt{{{7}^{2}}\times 6+\left( {{15}^{2}} \right)+57}=p$
 A 24 B (519)1/2 C 519 D 529
Question 2 Explanation:
$\displaystyle \begin{array}{l}p=\sqrt{49\times 6+225+57}\\=\sqrt{294+225+57}\\=\sqrt{576}=24\end{array}$
 Question 3
Find the value of p? $\displaystyle \sqrt{625.04}\times 16.94+204.001\div 17=p$
 A 4.18 B 4.41 C 425 D 437
Question 3 Explanation:
Taking approximate values
$\displaystyle \begin{array}{l}p=\sqrt{625}\times 17+204\div 17\\=25\times 17+204\times \frac{1}{17}\\=425+12=437\end{array}$
 Question 4
$\displaystyle 0.34\overline{33}+0.13\overline{33}=?$
 A $\displaystyle 0.47$ B $\displaystyle 0.47\overline{66}$ C $\displaystyle 0.\overline{48}$ D $\displaystyle 4.\overline{8}$
Question 4 Explanation:
$\displaystyle \begin{array}{l}0.34\overline{33}+0.13\overline{33}\\=\frac{3433-34}{9900}+\frac{1333-13}{9900}\\=\frac{3399+1320}{9900}=\frac{4719}{9900}\\=\frac{4766-47}{9900}=0.47\overline{66}\end{array}$
 Question 5
28.217 – 14.241 + 6.873 – 2.434 =p
 A 9.419 B 18.545 C 16.275 D none
Question 5 Explanation:
$\displaystyle p=28.217-14.241+6.873-2.434=18.415$
