The income of 'M' is Rs. ___ and the income of 'N' is 10% less than that of 'M'. 'M' saves 30% of his income while 'N' spends Rs. ___ less than the amount he saves. The sum of savings of 'M' and 'N' is Rs. 19,000. The values given in which among the following options, will fill the blanks in the same order, so as to make the statement true?
I. 20000, 8000
II. 18000, 11000
III. 22000, 6000

From I: Income of 'N' = 20000 X 0.9 = Rs. 18,000 Savings of 'M' = 20000 X 0.30 = Rs. 6,000 Let the savings of 'N' = Rs. 'Y' Then expenses of 'N' = Rs. (Y - 8000) So, Y + Y - 8000 = 18000 Or, 2Y - 8000 = 18000 Or, Y = (18000 + 8000) ÷ 2 = 13000 So, sum of savings of 'M' and 'N' = 6000 + 13000 = Rs. 19,000 So, statement I is true. From II: Income of 'N' = 18000 X 0.9 = Rs. 16,200 Savings of 'M' = 18000 X 0.30 = Rs. 5,400 Let the savings of 'N' = Rs. 'Y' Then, expenses of 'N' = Rs. (Y - 11000) So, Y + Y - 11000 = 16200 Or, 2Y - 11000 = 16200 Or, Y = (16200 + 11000) ÷ 2 = 13600 So, sum of savings of 'M' and 'N' = 5400 + 13600 = Rs. 19,000 So, statement II is true. From III: Income of 'N' = 22000 X 0.9 = Rs. 19,800 Savings of 'M' = 22000 X 0.30 = Rs. 6,600 Let the savings of 'N' = Rs. 'Y' Then, expense of 'N' = (Y - 6000) So, Y + Y - 6000 = 19800 Or, 2Y - 6000 = 19800 Or, Y = (19800 + 6000) ÷ 2 = 12900 So, sum of savings of 'M' and 'N' = 6600 + 12900 = Rs. 19,500 ≠ Rs. 19,000 So, statement III is false. Hence, option c.
