Explanation

15 : x :: 8 : 16 means 15 is to x as 8 is to 16

In a proportion: Product of means = Product of extremes  

So, 15 × 16 = x × 8

240 = 8x 

x = 240 / 8 = 30

Explanation

For TODAY: 

Letter positions: T(20) + O(15) + D(4) + A(1) + Y(25) = 65

Consonants (T, D, Y) = 3

Total: 65 + 3 = 68

For BOOK:

Letter positions: B(2) + O(15) + O(15) + K(11) = 43

Consonants (B, K) = 2

Total: 43 + 2 = 45

Explanation

There are 7 seats: 1 2 3 4 5 6 7

D is at the extreme right (because no one sits to the right of D).

So, D = 7.

There are 3 people between D and F.

Therefore, F = 3.

There are 2 people between F and A.

So, A = 6 (A cannot be 7 because D is already there).

G sits third to the left of B, and C is immediately to the right of B.

The only possible arrangement is:

G = 1

B = 4

C = 5

The remaining seat is 2, so E = 2.

Final arrangement:

1 2 3 4 5 6 7

G E F B C A D

People to the right of E are F, B, C, A, D = 5 people.

Explanation

Given:

• G is at the extreme right end → G = Position 7
• F sits exactly between C and G → C – F – G
  • Therefore: C = Position 5, F = Position 6, G = Position 7
• A sits third to the left of D → A = Position 1, D = Position 4
• B sits immediately to the right of A → B = Position 2
• E is not at either end → E = Position 3

Final Arrangement:

Explanation

• An optimist is a person whose outlook is cheerful.
• A pessimist is a person whose outlook is gloomy.
