I am getting answer as 26.60. Please Verify anyone. I am not getting the required answer :(

I am getting the same..can you post the solution?

---

In solution they simply say A =120 without giving solution and further calculate value of Y

---

I don't think they are right... :/

added the solution @minipanda

Answer 1

|6|2|3|  +
|6|5|  -             (2+3=5)
|1|                   (6-5=1)
|1|3|8|2| /        
|1|3|4|+          (8/2=4)
|1|7|*             (3+4=7)
|7|                 (1*7=7)

|7|3|^           (7^3 = 343)
|343|3|+
|346|

Therefore A=346

Y= 2*346+16 = 708

answer should be 26.60

Yes it is 26.60..but answer key is 16 :/

the answer is $26.60$ and $16$ is wrong i think.

---

correct answer is 26.6;

16 is wrong for sure;
