# Simplyfiy : $\left[3\frac{1}{4}÷\left\{1\frac{1}{4}-\frac{1}{2}\left(2\frac{1}{2}-\left(\overline{)\frac{1}{4}+\frac{1}{6}}\right)\right)\right\}\right]$

 A) 78 B) 88 C) 98 D) 108

Explanation:

Given exp =$\left[\frac{13}{4}÷\left\{\frac{5}{4}-\frac{1}{2}\left(\frac{5}{2}-\frac{3-2}{12}\right)\right\}\right]$$\left[\frac{13}{4}÷\left\{\frac{5}{4}-\frac{1}{2}\left(\frac{5}{2}-\frac{1}{12}\right)\right\}\right]$

$\left[\frac{13}{4}÷\left\{\frac{5}{4}-\frac{1}{2}\left(\frac{30-1}{12}\right)\right\}\right]$ = $\left[\frac{13}{4}÷\left\{\frac{5}{4}-\frac{29}{24}\right\}\right]$

= $\left[\frac{13}{4}÷\frac{30-29}{24}\right]$=78

Q:

Simplify

39.96% of 649.85 $\mathbf{÷}$13.07 = 45.14 - ?

 A) 25 B) 26 C) 27 D) 28

Explanation:

Q:

Simplify the fraction?

5 (2/7) - 3 (1/14) - 2 (1/14) - 1 (1/7) = ? + 3 (1/17)

 A) -4 (1/17) B) 5 (2/17) C) -2 (1/17) D) 3 (3/17)

Explanation:

Given fraction is 5 (2/7) - 3 (1/14) - 2 (1/14) - 1 (1/7) = ? + 3 (1/17)

It can be written as

(5 - 3 - 2 - 1) + (2/7 - 1/14 - 1/14 - 1/7) = ? +  3 (1/17)

-1 + 0 - 3 (1/17) = ?

=> ? = -4 (1/17)

Q:

5 + 2 x 10/2 = ?

 A) 15 B) 35 C) 10 D) 20

Explanation:

Using BODMAS Rule,

First solve division, mutiplication and Addition

So here 10/2 = 5

Then 2 x 5 =  10

Now, 5 + 10 = 15.

Hence, 5 + 2 x 10/2 = 15.
