Question

On a shelf, the first row contains 25% of the books in the second row and the third row contains 125%
of the books in the second row. If there are a total of 600 books on the shelf, then find the number of
books in each row.​

Please help me with the answer.

Answer 1

Answer:

let total no of books by

a,b and c = 125x+100x+75x

300x = 900 then x = 3

125x = 375

Answer 2

Step-by-step explanation:

This question is wrong .

At place of 25% there is 75% .

Solution...

First row = 75% = 75*x = 75x

Second row = x because of LCM we wil take 100x and because of percentage we had removed upon 100 from all numbers.

Third row =125%=125* x = 125x

Total books = 600

75x+x/1+125x/100 = 600

75x+100x+125x=600

300x=600

x=300/600

x=2

first row =75*2=150books

second row = 100*2= 200books

third row = 125*2=250books

check

sum of all = 150+200+250=600books

This is the right answer.
