Simplification-Test 1 (Based on VBODMAS rule)

Answer: Option D

Explanation

$\begin{array}{l}\text{In this question,}\\ \\ \text{104}-\text{21}\times \text{448}÷{\text{16+ 1013 = ?}}^{\text{2}}\\ \\ \Rightarrow \text{104 }-\text{ 21}\times {\text{28+1013 =?}}^{\text{2}}\\ \\ \Rightarrow \text{104}-{\text{588+ 1013 = ?}}^{\text{2}}\\ \\ \Rightarrow \text{529 = }{x}^2\\ \\ \Rightarrow \sqrt{x^2}=\sqrt{529}\\ \\ \Rightarrow x=23\end{array}$

Hence, Option D is correct.

Answer: Option D

Explanation

In this question 

we apply BODMAS rule,

$\begin{array}{l}\text{\hspace{0.17em}4003}\times \text{77}-\text{21015 =?}\times \text{116}\\ \\ \Rightarrow \text{ 308231- 21015=?}\times \text{116}\\ \\ \Rightarrow \text{\hspace{0.17em}287216 = ?}\times \text{116}\\ \\ \Rightarrow \text{\hspace{0.17em}? = }\frac{\text{287216}}{116}\text{ = 2476}\end{array}$

Hence, Option D is correct.

Answer: Option B

Explanation

In this question,

We apply BODMAS rule

$\begin{array}{l}(4444+40)+(645+25)+(3991+26)=?\\ \\ \text{= 111.1 + 25.8 + 153.5 = 290.4}\end{array}$

Hence, Option B is correct.

Answer: Option C

Explanation

In this question,

$\begin{array}{l}\text{118963- 107958- 9589 =?}\\ \\ \text{\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}= 118963}-\text{(1 07958 + 9589)}\\ \\ \text{\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}= 118963}-\text{(117547) = 1416}\end{array}$

Hence, Option C is correct.

Answer: Option D

Explanation

In this question

$\begin{array}{l}\text{(5696 + 4}-\text{?)}\times \text{5 = 1020}\\ \\ \Rightarrow \text{\hspace{0.17em}(1424 - ?)}\times \text{5 = 1020}\\ \\ \Rightarrow \text{\hspace{0.17em}1424}-\text{?=204}\\ \\ \Rightarrow \text{\hspace{0.17em}? =1424}-\text{204}\\ \\ \Rightarrow \text{\hspace{0.17em}? = 1220}\end{array}$

Hence, Option D is correct.
