Answer:
Romance books ordered = 65
Mystery books ordered = 775
Science Fiction book Ordered ≈ 116
Step-by-step explanation:
Total number of books ordered in the library = 956
Let us assume the number of romance books ordered = m
⇒Number of mystery books ordered = 12 x (Number of romance books)
= 12 x(m) = 12 m
Also,number of science books ordered = 52 +(Number of romance books)
= 52 + m
Now, according to the question:
Number of { romance books + mystery books + science books} = 956
or, m + ( 12 m ) + (52 + m) = 956
or, 14 m = 956 - 52
or, 14 m = 904
⇒ m = 904/ 14 = 64.6
So, the number of romance books ordered = 64.6 ≈ 65
Number of mystery books ordered = 12 m = 12 x 64.5 = 775
Number of science fiction book ordered = = 52 + m = 116.6 ≈ 116
