Question
Six students (D, E, F, G, H and I) sit in a linear row
facing south in a classroom but not necessarily in the same order. One person sits between D and F. Two persons sit to the right of F. H sits third to the right of G. G doesn’t sit adjacent to E or I. Who sits second to the left of G?ÂSolution
F sits third from extreme left end of row. One person sits between D and F. H sits third to the right of G. G doesn’t sit adjacent to E or I. We get D sits either at extreme left or second from extreme right end of row. H sits at extreme left end of row. Either I or E sits at extreme right end of row. The final arrangement is as follows: Either I or E sits second to the left of G. H        I/E      F         G        D        E/I     Â
? × 5.5 = √1225 + 40% of 30% of 37.5% of 5000 – 63
26 X √25 + 15 - 80% of 120 = ?2Â
121/? = ?/144
- What will come in place of (?), in the given expression.
(5³ + 3²) × 2 = ? (125 × 12 × √8100) ÷ 150 = ?
40500 ÷ 30 × 42 – 45% of 2400 =? + 42100
(75 + 0.25 × 10) × 4 = ?2 - 14
Simplify:

What will come in the place of question mark (?) in the given expression?
(252 + 198) ÷ ? + 126 ÷ 3 = 144 ÷ 2
