Answer 1

Answer:

Step-by-step explanation:

Assume total number of books is X

Then

Marathi books = 50% of X = X(50/100) = X/2

English books = 1/3 of Marathi books = 1/3 × X/2 = X/6

Mathematics books = 25% of English books = 25/100 × X/6 = 1/4 × X/6 = X/24

Total number of books = Marathi + English + Mathematics + Remaining

X = X/2 + X/6 + X/24 + 560

X =(12X + 4X + X)/24 + 560

X =17X/24 + 560

X - 17X/24 = 560

7X/24 = 560

X = 560×24/7 = 1920

Total number of books is 1920
