Answer: Option E

Explanation

In this question,

$\begin{array}{l}\text{4848}÷\text{24}\times \text{11}-\text{222 =?}\\ \Rightarrow \text{ 202}\times \text{11}-\text{222 = ?}\\ \Rightarrow 2222-222=?\\ \Rightarrow ?=2000\end{array}$

Hence, Option E is correct.

Answer: Option E

Explanation

In this above question,

 $$\begin{gathered} \begin{array}{l}\text{Here, ?}\\ \text{= 653}\times \text{749\hspace{0.17em}}\\ \text{= (701}-\text{48)}\times (701 + 48\\ {\text{= (701)}}^{\text{2}}-{\text{(48)}}^{\text{2}}\\ [\because a^2-b^2=(a+b\left)\right(a-b\left)\right]\end{array} \\ =491401-2304=489097 \end{gathered}$$

Hence, option E is correct.

Answer: Option E

Explanation

In this question,

$\begin{array}{l}\text{ = 460}\times \text{15}-\text{5}\times \text{20 = ?}\\ \\ \Rightarrow \text{\hspace{0.17em}6900- 100= 6800}\end{array}$

Hence, Option E is correct.

Answer: Option D

Explanation

In this question,

$\begin{array}{l}\Rightarrow \text{5163}-\text{4018+3209 = ?}\\ \\ \Rightarrow \text{\hspace{0.17em}? = 5163+3209 - 4018}\\ \\ \Rightarrow \text{? = 8372 - 4018 = 4354}\end{array}$

Hence, Option D is correct.
