1. C lives on the third numbered floor. 2. Only two persons live between the floors of C and O. 3. Only one person lives between the floors of M and N. 4. M lives above N.
5. Only one person lives between the floors of C and D. 6. C lives on one of the floor below the floor of M. 7. P lives on the floor immediately above the floor on which B lives.
There is no space for P and B in CASE1A so CASE1A is cancelled out. Final arrangement:
24% of 400 × 16% of ? = 384
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
22 * 6 + 45% of 90 + 65% of 180 = ?
[(36 × 15 ÷ 96 + 19 ÷ 8) × 38] = ?% of 608
36×?² + (25% of 208 +13) = 60% of 2400 + 17×18
(360 - ?)/(25% of 96) = 13
Solve.
15.73 +13.25 +16.73 – 28.71 = 5 ×?
(11/12) × (18/22) × (4/3) + 3 = ?2
