Anglo-Chinese School (Primary) P5 SA2 2006 Math Question (Q47)

In a bookshop, 64% of the books are Chinese books. The rest are Malay and Tamil books. The ratio of the number of Malay books to the number of Tamil books is 3 : 1. There are 110 more Chinese books than Tamil books.

a) What percentage of the books are Malay books?
b) How many Chinese books are there?


Solution



4 units ----- 36%

1 unit ----- 36% divided by 4 = 9%

(Chinese books) – (Tamil books) ----- 110 books

64% - 9% ---- 110 books

55% ----- 110 books

1% ----- 110 books divided by 55 = 2 books


Q(a)

(Malay books) 3 units ----- 3 units x 9% = 27%

Answer: 27% of the books are Malay books.


Q(b)

(Chinese books) 64% ----- 64 x 2 books = 128 books

Answer: There are 128 Chinese books.
