Solution -
Let,
Total number of books = 1000x
number of books in Hindi = 60% of 1000x
= (60/100) × 1000x
= 600x
Remaining books = 1000x - 600x
= 400x
number of books in English = 60% of the remaining books
= (60/100) × 400x
= 240x
Given,
Number of books in English = 4800
240x = 4800
x = 4800/240
x = 20
Total numbeer of books = 1000x
= 1000 × 20
= 20000
Number of Hindi books = 600x
= 600 × 20
= 12000
Remaining books = 20,000 - [12000 + 4800]
= 20,000 - 16800
= 3200
Therefore,
The number of books in malayalam is 32,00
Hence,
The correct option is (d) none of these.
