Step-by-step explanation:

Given : Ratio of story books and textbooks is 2 : 5 . He has 4 story books.

To find : Number of textbook he has.

Solutions :

Let x be the constant of the ratio of the books.

Thus the ratio becomes,

2x and 5x

It is given that story books are 4

Therefore, 2x =4

Thus, x=4/2

x=2

Putting the value of x in 5x we will get number of textbook

Therefore 5x =5*2=10

Therefore he had 10 textbooks

story book :- 2x=4

x=4/2=2

Text books :- 5x=5×2=10
