Trial and error method.

if we interchange $+ and -$  answer would be 2952

if we interchange $+ and \div$ answer would be 20.71

if we interchange  $\div and \times$ answer would be 20689.07

if we interchange  $\times and -$ answer would be  520

By interchanging ‘$+$’ and ‘$-$’

(A) : $13 – 14 \times 3 + 7 = 48$

L.H.S. $\equiv13+14\times3-7$

= $13+42-7=48=$ R.H.S.

=> Ans – (A)

if we interchange 3 and 5 then-

6 + 3 $\times$ 2 – 5

= 6+6-5

=7

If we interchange ‘$\times$ and $\div$’ then-

14 + 9 $\times$ 24 $\div$ 3

= 14+72

= 86

$11 \div 9 – 63 + 7 \times 2$

= $11 + 9 – 63 \div 7 \times 2$

=  $11 + 9 – 9 \times 2$

= 11 – 9 =2

So , the answer would be option a )2.

On interchanging the two signs $+$ and $\times$

we get the equation as

$11+6 \div 18\times 54$

or $11+1\div 3\times 54 =29$

$29=29$ which is true

On interchanging the signs $\times and \div$

we get the equation as

$16+19\div 51 \times 153 -12$

or $16+19 \times 3-12$

16+57-12=61

$9 – 2 \times 4 \div 6 = -3$

By option (2) 6 and 2, on interchanging we get, $9 – 6 \times 4 \div 2 = -3$

Using BODMAS rule, we get, $9 – 6 \times 2 = -3$

9 – 12 = -3

-3 = -3

Hence LHS = RHS.

For this question we have to go by option, so when we replace $- and \times$ as per option A,

$19 + 63 \div 7 \times 8 – 12 = 79$

$19 + {\frac{63}{7}}\times 8 – 12 = 79$

$19 + {9\times8} – 12 = 79$

$19 + 72 – 12 = 79$

$79 = 79$

Therefore option A is the answer.

$6 + 9 \times 2 – 3 \div 4 = 8$

this results in a fraction so in order to get a whole number which is 8 it is important to place divide symbol such that a whole number is obtained

now if  $- and \div$ is interchanged 9 gets divided by 3 thus resulting in a whole number

$6 + 9 \times 2\div 3- 4$ (using BODMAS rule)

$6 + \frac{ 9 \times 2}{ 3} – 4$

= 6+ 6 – 4 = 8

going by the options

A) 8 and 3

$7 + 3 \div 4 \times 8$=  $7 + \frac{8}{4}\times 3$ = 7 + 6 = 13 (Option A is correct )

B) 8 and 4

$7 + 4 \div 8 \times 3$ =  $7 + \frac{4}{8}\times 3$ = 7 + $\frac{3}{2}$= $\frac{17}{2}$   (option B is incorrect)

c) 7 and 3

$3 + 8 \div 4 \times 7$ = 3+$\frac{8}{4}\times 7$ = 3 +14 = 17 (option C is incorrect)

d) 3 and 4

$7 + 8 \div 3 \times 4$ = 7+ $\frac{8}{3}\times 4$ = 7 +$\frac{32}{3}$ = $\frac{53}{3}$  (option D is incorrect)

Given, 11+16 $\times$ 12  $\div$ 4  – 2 = 21

These type of questions can be quickly solved by checking options.

So,from the options we get option A would be correct.

On solving,11+16-12 $\div$ 4  $\times$2 

$\Rightarrow$  27 – 6 = 21.

given  3 + 2 ÷ 1 × 4 – 7

on interchanging 4 and 7

BODMAS rule{ brackets > of > division > multiplication > addition > subtraction }

we get  3 + 2 ÷ 1 × 7 – 4 ( using BODMAS rule)

3+$\frac{2}{1} \times$ 7 -4 = 3 + 2 $\times$ 7  – 4 = 3 + 14 – 4 = 13
