Then, 3 : 5 = 2.4 : x x = 5 x 2.4 = 4. 3 Total population below poverty line = (2.4 + 4) = 6.4 million. If Nq be the total population of State Q, then, 25% of Nq = 6.4 million Nq = 6.4 x 100 million = 25.6 million. 25 For State T: Male population below poverty line = 6 million. Let the female population below poverty line be y million. Then, 5 : 3 = 6 : y y = 3 x 6 = 3.6. 5 Total population below poverty line = (6 + 3.6) = 9.6 million. If Nt be the total population of State T, then, 15% of Nt = 9.6 million Nt = 9.6 x 100 million = 64 million. 15 Thus, Required ratio = Nq = 25.6 = 0.4 = 2 . Nt 64 5
