Question

'x' means 'added to' ; '+' means 'subtracted from' ; .;. means 'multiplied by'

; , _' means 'divided by' then 24 + 36 _ 12 x 8 + 4 will be equal to which of the

following:

(1) 36 (2) 3 (3) 5 (4) -20​

Answer 1

Instructions provided here -

'x' means 'added to' ; '+' means 'subtracted from' ; .;. means 'multiplied by'

According to given instructions -

24 + 36 - 12 x 8 + 4

24 - 36 × 12 + 8 - 4

According to BODMAS RULE -

24 - 432 + 8 - 4

24 - 440 - 4

- 416 - 4

- 420

Answer 2

Correct question is "'x' means 'added to' ; '+' means 'subtracted from' ; '÷' means 'multiplied by' ; '-' means 'divided by' then 24 + 36 _ 12 x 8 + 4 will be equal to which of the following: (1) 36 (2) 3 (3) 25 (4) -20"

Answer:

Required value is 25.

Step-by-step explanation:

Given,'x' means 'added to' ; '+' means 'subtracted from' ,'÷'means 'multiplied by' ,'-' means 'divided by

It is also given,

$24 + 36 - 12 \times 8 + 4$

We are changing all sign according to question and have,

$24 - 36 \div 12 + 8 - 4$

Now we can solve this by BODMAS rule.

By BODMAS rule,

Bracket - Of - Division - Multiplication - Addition - Subtraction

So,

$24 - \frac{36}{12} + 8 - 4 \\ = 24 - 3 + 8 - 4 \\ = 21 + 4 \\ = 25$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
