Two persons A and B wear glasses of optical powers (in air) `P_1 = + 2 D` and `P_2 = + 1D` respectively. The glasses have refractive index 1.5. Now they jump into a swimming pool and look at each other. B appears to be present at distance 2m (f rom A) to A. A appears to be present at distance 1m (from B) to B. The refractive index of water in the swimming pool, in the form `(X)/(10)` and find X.
