Question

169 digits are used in all to number the pages of book how many pages book contain​

Answer 1

Answer:

Let the number be x

Number be added with 5, it will be x + 5

number is multiplied by 6, it will be 6 (x + 5)

the answer is 180

6 (x + 5) = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 150/6

x = 25

Thus the original number is 25

Answer the original number is 25

Now checking the correctness of answer by putting the value of number in the equation

6 (x + 5) = 180

6 ( 25 + 5) = 180

6 (30) = 180

180 = 180
