Answer:
Answer : 2,700 Books Of Science
Step-by-step explanation:
No.of Math Books = 1800
No.of English Books = 1200
Ratio :
English Books : Math Books = Maths Books : English Books
= 1200 : 1800 = 1800 : x
= 1200 : 1800 :: 1800 : x
Product Of Means = 1800 × 1800 = 3 , 240 , 000
Product Of Extremes = 1200 × x = 1800x
Product Of Means = Product Of Extremes
3 , 240 , 000 = 1200x
x = 3 , 240 , 000 ÷ 1200
x ( English Books ) = 2700
∴ The Number Of English Books Are 2,700
