All are correct except 4. The Kuroshio is a north-flowing ocean  current on  the  west side  of  the  North Pacific  Ocean.  It is similar to the Gulf Stream in the North  Atlantic  and  is  part  of  the North  Pacific ocean  gyre.  Like  the Gulf  stream,  it  is  a  strong western boundary  current.  Gulf  stream  is not present in west Pacific coast

From I and II,
Length = 3x = 48 m
∴ x = 16
Breath = 2x = 32 m
Hence, Area of floor = 48 × 32
Cost of flooring = 48 × 32 × 850 = ₹ 1305600
From I and III, 2(l +b) = 160
2(3x + 2x) = 160
10x = 160
∴ x = 16
∴ Length = 3 × 16 = 48 m
Breadth = 2x = 32m
Cost of flooring = (48 × 32) × 850 = ₹ 1305600
Similarly, from II and III, we can find
l = 48 m
b = 32 m
and Total cost of flooring = ₹ 1305600
