All 20 students in a class are standing in a row facing north. Raveena is 10th from the right end while Deepa is 4th from the left end. How many people stand between Raveena and Deepa?

A group of numbers/symbols is coded using letter codes as per the codes given below and the conditions that follow. The correct combination of codes following the conditions is your answer. Note: If none of the conditions apply, then the codes for the respective number/symbol are to be followed directly as given in the table. \[ \begin{array}{|c|cccccccccccccc|} \hline \text{Numbers/symbols} & \% & 6 & 2 & 8 & * & 3 & \& & 7 & @ & 9 & \$ & 5 & + & 4 \\ \hline \text{Codes} & U & G & W & D & F & K & L & S & V & B & E & J & H & C \\ \hline \end{array} \]Conditions: (i) If the first element is a symbol and the last element a perfect square, the codes for these two (the first and last elements) are to be interchanged. (ii) If both the second and third elements are symbols, the third element is to be coded as the code for the second element. (iii) If the first element is a symbol and the fourth element is an odd number, the first and fourth elements are to be coded as ©. What will be the code for the following group? % 5 * 7 $

If A stands for , B stands for , C stands for + and D stands for, what will come in place of the question mark (?) in the following equation?

36 B 39 A 39 D 48 C 20 = ?

Seven people B, C, D, I, J, K, and L are sitting around a circular table facing the centre of the table. L sits third to the left of I. Only one person sits between K and B, when counted from the left of B. C sits third to the right of D. C sits to the immediate right of L. J is not an immediate neighbour of L. How many people sit between J and B, when counted from the right of J?

Refer to the following series and answer the question (all numbers are single digit numbers only). Counting to be done from Left to Right only.

(Left) 5 8 7 7 6 3 5 4 8 8 6 2 5 9 2 7 2 4 4 9 9 (Right)

How many such odd digits are there each of which is immediately preceded by a perfect square and also immediately followed by an odd digit?

Refer to the following number and symbol series and answer the question that follows (all numbers are single-digit numbers only). Counting to be done from left to right only.

(Left) 1 5 7 8 = 6 9 2 + 5 7 3 % 7 8 $ 4 1 5 # 8 @ & 4 9 6 (Right)

How many such symbols are there, each of which is immediately preceded by an odd number and also immediately followed by an even number?

Refer to the following number and symbol series and answer the question that follows (all numbers are single-digit numbers only). Counting to be done from left to right only.

(Left) 1 5 7 8 = 6 9 2 + 5 7 3 % 7 8 $ 4 1 5 # 8 @ & 4 9 6 (Right)

How many such symbols are there, each of which is immediately preceded by an odd number and also immediately followed by an even number?

What should come in place of the question mark (?) in the given series:

221, 223, 227, 233, 241, ?

What should come in place of the question mark (?) in the given series:

88, 91, 97, 106, 118, ?
