Question

A vertical U-tube of uniform inner cross-section contains mercury in both sides of its arms. A water column of length 20 cm is poured into one of its arms. Oil of unknown density is poured into the other arm upto a height of 19.5 cm such that the upper surfaces of oil and water are in the same horizontal level. The density of oil is?
