Among four books, Book1 is twice as heavy as Book 2. Book 3's weight is half of Book 2's weight. Book 4 is 60 grams more as compared to Book 2 but 60 grams less as compared Book 1. Which book is heaviest?
Book 1
Book 2
Book 3
Book 4
A.
Book 1
Book 1 = 2 (Book 2) ...(i)
Book 2 = 2 (Book 3)
Book 4 - Book 2 = 60 ...(ii)
and
Book 1 - Book 4 = 60 ...(iii)
2 x Book 2 - Book 4 = 60 ...(iv) [Using (i)]
Adding (ii) and (iv)
Book 2 = 120
∴ Book 1 = 240
∴ Book 3 = (120/2) = 60
∴ Book 4 = (120 + 60) = 180
Thus, Book 1 is the heaviest.
