Step-by-step explanation:
Sum is the addition of two or more integers. The sum of negative and positive integers must always consider the sign before a number for the given numbers, we shall add them one by one as follows
-18+12=-6
-6+-27=-33
-33+-9=-42
-42+16=-26
Therefore, the sum is -26 which is not among the options given although this is the right answer

Answer:
The total number of boys = 105
Step-by-step explanation:
The ratio of boys to girls = 3: 4
⇒ For every 3 boys, there are 4 girls.
Now, total number of students = 245
Let the common ratio of boys to girls is k.
So, 3k + 4k = 245
or , 7k = 245
⇒ k = 245/7 = 35
⇒ k = 35
Hence, the number of boys = 3k = 3 x 35 = 105
and number of girls = 4k = 4 x 35 = 140
