so, BUT = 5*\$

2.5 4 8 6 7
64 = 8 × 8

3.J(-1) = I
U(-1) = T
N(-1) = M
G(-1) = F
L(-1) = K
E(-1) = D
Similarly, NORM = MNQL

4.Letters = IEST
Meaningful words = SITE, TIES

5.Deepika > Priyanka....(i)
From three statements,
Kareena > Sradhha > Huma > Deepika > Priyanka

6.Abhinav's rank is 6th from the top.
Therefore, his rank from the bottom = 40 - 6 + 1 = 35th

7.8 2 5 6 4 7
2 4 5 6 7 8

8.18 - 6 ÷ 8 × 4
= 18 + 6 - 8 ÷ 4
= 18 + 6 - 2
= 22

9.20 ÷ 10 + 8
= 20 - 10 × 8
= 20 - 80
= - 60

10.16 + 4 × M = 8
or, 16 × 4 ÷ M = 8
or, 8M = 64
or, M = 8
