What's A + B = ?
I found A=60 and B=63x4=252, thus A+B=60+252=312; but, source says that's wrong answer.
Source: This question was asked in YTU exam for int'l students in 2018. I have discussed about them in my other posts.
Possible answers are: 158, 204, 112, 148 and 168. Correct one is commented by @Damila below, I don't want to write it here. Thanks.
