Answer 1

Answer:

Step-by-step explanation:

let the no of books in second row =x

the no number of first row = x *25/100 =x/4

no of the boofs in the thirs row = x *125/100 =5x/4

x +x/4 + 5x/4 =600

(4x +x+ 5x)/4 =600

10x =2400

x=240

the number of books in the first row = x/4 =240/4=60

the number of books in the second row =x =240

the number of the books in the third row =5x/4 =(5*240)/4

                                                                              =5*60

                                                                              = 300
