       P # Q, means subtract

       P % Q, means add

       P @ Q, means multiply

then, 70 # 30% 80 $ 20 @ 10 = ?

(A) 60

(B) 80

(C) 20

(D) 10

Answer 1

Question :

P $ Q, means divide

P # Q, means subtract

P % Q, means add

P @ Q, means multiply

then, 70 # 30% 80 $ 20 @ 10 = ?

(A) 60

(B) 80

(C) 20

Solution : (B) 80

As per your question,

$\tt{ = 70 - 30 + 80 ÷ 20 × 10} \\ \\ \tt{Using \: \: BODMAS \: \: rule,} \\ \\ \tt{ = 70 - 30 + 4 × 10}$
$\tt{ = 70 - 30 + 40} \\ \\ \tt{ = 40 + 40} \\ \\ \tt{ = 80}$

Hence,

Option B) 80 is the answer.

Answer 2

❤$\mathfrak{\huge{Hola!}}$❤

Given that:

P $ Q = division
P # Q = subtraction
P % Q = addtion
P @ Q = multiplication

Therefore,

70 # 30 % 80 $ 20 @ 10

Will be = 70 - 30 + 80 ÷ 20 × 10

We need to use the $\textbf{BODMAS}$ rule here;

=》 70 - 30 + 4 × 10

=》 70 - 30 + 40

=》 70 + 10

=》 $\textbf{80}$

Answer: $\mathcal{ (B) 80}$
