The income of 'A' is Rs. ___ and the income of 'B' is 15% more than that of 'A'. 'A' saves 48% of his income while 'B' spends Rs. ___ more than the amount he saves. The sum of savings of 'A' and 'B' is Rs. 16,000. 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. 15000, 3100
II. 20000, 10200
III. 18000, 8000

From I: Income of 'B' = 15000 X 1.15 = Rs. 17,250 Savings of 'A' = 15000 X 0.48 = Rs. 7,200 Let the savings of 'B' = Rs. 'Y' Then expenses of 'B' = Rs. (Y + 3100) So, Y + Y + 3100 = 17250 Or, 2Y + 3100 = 17250 Or, Y = (17250 - 3100) ÷ 2 = 7075 So, sum of savings of 'A' and 'B' = 7200 + 7075 = Rs. 14,275 ≠ Rs. 16,000 So, statement I is false. From II: Income of 'B' = 20000 X 1.15 = Rs. 23,000 Savings of 'A' = 20000 X 0.48 = Rs. 9,600 Let the savings of 'B' = Rs. 'Y' Then, expenses of 'B' = Rs. (Y + 10200) So, Y + Y + 10200 = 23000 Or, 2Y + 10200 = 23000 Or, Y = (23000 - 10200) ÷ 2 = 6400 So, sum of savings of 'A' and 'B' = 9600 + 6400 = Rs. 16,000 So, statement II is true. From III: Income of 'B' = 18000 X 1.15 = Rs. 20,700 Savings of 'A' = 18000 X 0.48 = Rs. 8,640 Let the savings of 'B' = Rs. 'Y' Then, expense of 'B' = (Y + 8000) So, Y + Y + 8000 = 20700 Or, 2Y + 8000 = 20700 Or, Y = (20700 - 8000) ÷ 2 = 6350 So, sum of savings of 'A' and 'B' = 8640 + 6350 = Rs. 14,990 ≠ Rs. 16,000 So, statement III is false. Hence, option b.
