Question

366 पृष्ठों वाली पुस्तक की पृष्ठ संख्या लिखने हेतु कितने अंकों की आवश्यकता
होगी?
​

Answer 1

Answer:

990

Step-by-step explanation:

From 1 to 366,

Numbers of single digit = 9 ( i.e 1, 2, 3, 4, 5, 6, 7, 8, 9 ),

So, digits = 9 × 1 = 9

Numbers of double digits = 90  ( i.e. 10, 11, 12,........99)

So, digits = 90 × 2 = 180,

Number of triple digits = 267 ( i.e. 100, 101, ........366 )

So, digits = 267 × 3 = 801,

Hence, the total digits = 9 + 180 + 801 = 900
