The expression 5 -2 - 3 * 5 - 2 will evaluate to 18, if

A.	- is left associative and * has precedence over -
B.	- is rightt associative and * has precedence over -
C.	- is right associative and - has precedence over *
D.	- is left associative and - has precedence over *

error in question this is actual question

---

Then answer is C ?

---

@MiNiPanda   yes 

---

Someone write the expression with braces pls

---

As claimed by Sumit, the question is misprinted..according to the image shared by him..For C ..
(5-(2-3))*(5-2) =18

---

it's clearly C.

---

if - is right associative and - has precedence over * our expression will be evaluated as

5-2-3*5-2= 5-2-3*(5-2) = 5-2-3*3 = 5-(-1)*3 = 6*3=18. so i think C is correct option.

---

thx

The question is wrong. The real expression is $5-2-3*5-2$.
