A20

B40

C35

D25

Answer:

A. 20

Read Explanation:

Substitute the symbols with their meanings:

  • J = +

  • K = −

  • L = ×

  • M = ÷

So,

20;M;4;L;3;J;520 ; M ; 4 ; L ; 3 ; J ; 5

20÷4×3+520 \div 4 \times 3 + 5

Using the standard order of operations (÷ and × from left to right, then +):

20÷4=520 \div 4 = 5
5×3=155 \times 3 = 15
15+5=2015 + 5 = 20

Answer:(20)Answer: (\boxed{20}).
