Answer:

Step-by-step explanation:

let the number of books in second row be x.

1st row =25%+x =25/100+x =25+100x/100 = 125/100x

2nd row=25%-x

=25/100-x = 100-25x/100 = 75/100x

Total books = 900

900=75/100x + 125/100x + x

900= (75 +125+100)x/100

900=300/100x

x = 900*100/300

x = 300

1st row books = 125/100x

= 125/100 *300(cancel out)

=☺️375☺️Answer
