Question

any library the number of books increased by 9% over the previous year of the book number of Buxar now is 62 130 how many books were in the previous year

Answer 1

Greetings..!

Let the number of books previous year be 100x.

Increase percentage yearly = 9% = 9% of 100x

(9/100)*100x = 9x

Hence, increased no of books next year = 100x + 9x = 109x

So,this should be equal to the no of books given in question,as :

⇒109x = 62130

⇒x = 62130/109  {transposing 109 to RHS and thus changing action(multiply         into division}

= 570

Hence, no of books = 100 × x = 100×570=57000

Answer : Hence, no of books in previous year = 57000
