for 337-25+48=360 (without the new value of 2nd shelf)
The reason why is divided by 9 unit it is because you do not know how much is been added to the 2nd shelf. But you know that the original book value is 4 times the book after it is been added.
So it is deduced that both new value of shelf 1 and 3 are 4 units each. And thus u will get 9 units (8 units[ new 1 and 3 shelf ] + 1unit [old value of shelf 2]).
