Q1. Ans: (36)

Q2. Ans: (12)

Q3. Ans: (18)

Q4. Ans: (26)

Given,

Arjun attempted 125 problems and got 67 points i.e., he already lost $60 \times 1 / 6 = 10$ points for unattempted problems and for every failure he loses another 4/3 (1 mark of the question and 1/3 rd negative marks) points of this 115 points.

$125 - 10 - \frac { 4 } { 3 } ( F ) = 67$

$F = 36$

Total successful attempts $= 125 - 36 = 89$

In Dupe, number of successful attempts $= 17 - 6 = 11$

Net score $= 11 - \left( 6 \times \frac { 1 } { 3 } \right) - 18 \times \left( \frac { 1 } { 6 } \right) = 6$

Net score in Dance = 12

Number of failures in Digit = 6

Now, sum of number of unattempted problems and successful attempts in Digit is 34 and as the total score in Digit is a integer. the number of unattempted problems must be a multiple of 6.

By trail and error,

Number of unattempted problems = 18

Number of attempted problems = 22

Number of successful attempts = 16

Net score = 11

Number of failures in Dance = 3

Net score = 12

By trail and error,

Number of unattempted problems. which must be a multiple of 6= 12

Number of successful attempts = 15

Now total successful attempts = 89

Number of successful attempts in Dice = 17

Number of failures = 12

Net score = 12

Number of failures in Dynasty = 9

Number of unattempted problems in Dynasty = 6

T.P = Total Problems; PA = Problems Attempted:

S.A = Successful Attempts; F = Failures;

N = Net score.
