1. B lives in an even numbered flat on lowermost floor i.e. B lives on floor ground floor in flat 2. 2. K lives in an even numbered flat on floor number 2. B and C live on same floor. E lives immediately above Nand the numbers of their flats is same. So, Now, C either lives immediate west or east of B which means E either lives in flat 3 or flat 1. So, we have two possibilities. Case I: When C and E live on flat – 3: 3. G and A live on same floor. I lives to the immediate west of G. G lives immediately below the vacant flat and the flat number of vacant flat and G is same. A lives in flat – 1. There is one floor between G and F. Now, G lives immediately below vacant flat so, the vacant flat must be in topmost floor. Case I: When C and E live on flat – 3:
5. D lives somewhere above J in same flat number, but not on flat 3. Now, we cannot fix D and J in same flat number in case II, so, case II is invalid. The final arrangement is as follows
(125 × 12 × √8100) ÷ 150 = ?
(60/15) × 25 + 15 2 – 18% of 200 = ? 2
78.89 × 81.03 – (16.83)² + 8.33% of 9602.87 = ? – 50.23
81 ÷ 0.09 × 1.4 – 1223=?
85% of 620 + ? % of 1082 = 4855
[(4√ (7) +√ (7))× (7√ (7) + 6√ (7))] - 87 = ?
...24% of 150% of 500 + 140 = ? × 8
(-251 × 21 × -12) ÷ ? = 158.13
144% of 200 + 11% of 900 + 10% of 20 =?
1404 ÷ 26 x 3 + 7 = ?2
