Correct answer: A. 31 : 31 : 60
Explanation
City C now: I = 4,80,000, II = 4,80,000, III = 9,60,000. Next year: I = 4,80,000 − 16,000 + 32,000 = 4,96,000; II = 4,80,000 + 16,000 = 4,96,000; III = 9,60,000. Ratio = 496 : 496 : 960 = 31 : 31 : 60.शहर C में अभी: I = 4,80,000, II = 4,80,000, III = 9,60,000। अगले वर्ष: I = 4,80,000 − 16,000 + 32,000 = 4,96,000; II = 4,80,000 + 16,000 = 4,96,000; III = 9,60,000। अनुपात = 496 : 496 : 960 = 31 : 31 : 60।More Data Interpretation questions
