Answer:
The answer is 27 books
Step-by-step explanation:
Because
Step = LET THE THE NUMBER OF BOOKS WHICH HAS GREEN COVER BE 2X AS GIVEN IN THE QUESTION
AND LET THE NUMBER OF BOOKS WHICH HAS BROWN COVER BE 3X AS GIVEN IN THE QUESTION
As we know that there are 18 books with green cover
That is,
2x = 18
x = 18/2
= 9
The number of books which has brown cover are -
= 3x
= 3 X 9(x = 9)
= 27 books
