Question

(8) 30 - [15 - {8 - (6 - 8 - 7)}] + 14÷7
​

Answer 1

Solution :-

This question can be solve by using the rule of BODMASS $.$

BODMASS Stands for bracket open division, multiplication , addition and subtraction .

Let's start,

= 30 - [ 15 - { 8 - ( 6 - 8 - 7 )}] + 14 / 7

= 30 - [ 15 - { 8 - ( 6 -15 )}] + 14 / 7

= 30 - [ 15 - { 8 - ( - 9 )}] + 14 / 7

= 30 - [ 15 - { 8 + 9 }] + 14/7

= 30 - [ 15 - 17 ] + 14/7

= 30 -[ - 2 ] + 14/7

= 30 + 2 + 14/7

= 30 + 2 + 2

= 32 + 2

= 34

Answer 2

Step-by-step explanation:

$\\ \tt\longrightarrow 30-\left[15-\left\{8-(6-8-7)\right\}\right]+\dfrac{14}{7}$

$\\ \tt\longrightarrow 30-\left[15-\left\{8-(6-15)\right\}\right]+2$

$\\ \tt\longrightarrow 30-\left[15-\left\{8-(-9)\right\}\right]+2$

$\\ \tt\longrightarrow 30-\left[15-(8+9)\right]+2$

$\\ \tt\longrightarrow 30-\left[15-17\right]+2$

$\\ \tt\longrightarrow 30-(-2)+2$

$\\ \tt\longrightarrow 30+2+2$

$\\ \tt\longrightarrow 30+4$

$\\ \tt\longrightarrow 34$
