Step-by-step explanation:
Method 1 : ratio
Vikram sold 22 books in 18 days
Ratio = 22:18 =11:9
Tanya sold 19 books in 19 days
Ratio= 19:19 =1:1
Since 11:9 is greater than 1:1 , Vikram has sold more books than Tanya .
Method 2 = finding the rate
Vikram sold 22 books in 18 days
Rate of selling books = 22/18 = 1.22222
Tanya sold 19 books in 19 days
Rate of selling books = 19/19
Since rate of Vikram is higher than Tanya , He sold more books than her.
I hope this would help you
