20 Practice Questions for Ranking Topic in Reasoning Ability

1) Rina ranked 12^th from the bottom and Tina ranked 21^st from the top in an exam. If 9 students ranked between Rina and Tina and Tina’s rank is better than Rina’s rank. Then, how many students are there in the class?

Solution: 

Rank of Rina from the bottom: 12^th

Rank of Tina from the top: 21^st

If 9 students ranked between Rina and Tina, then Rank of Rina from the top is: 21 + 10 = 31^st

Number of students ranked after Rina is: 11

Therefore, Total number of students in the class = 31 + 11 = 42

2) In a class, there are 7 kids K, L, M, N, O, P and Q of different heights. Q is shorter than only O. Only four kids are shorter than K. L is just shorter than K. M is taller than P but he is not the second shortest kid. P is not the shortest kid. Who is the shortest kid?

Solution:

Clues:

1. Q is shorter than only O.
2. Only four kids are shorter than K.
3. L is just shorter than K.
4. M is taller than P but he is not the second shortest kid. P is not the shortest kid

Inference:

From Clue 1, we get, O is the tallest kid and Q is the 2^nd tallest kid and five kids are shorter than Q.

From Clue 2, we get, K is the 5^th tallest kid.

From Clue 3, we get, L is the 4^th tallest kid.

From Clue 4, we get, M is the 3^rd tallest kid, P is the 2^nd shortest kid and N is the shortest kid.

Therefore, the arrangement we get based on the heights of the kids is:

O (tallest) > Q > K > L > M > P > N (shortest)

So, we can say from the above arrangement that N is the shortest kid.

Answer Keys and Solutions

Solution 1: E)

Clues: R is taller than at least two persons but not the tallest. Q is taller than P, who is taller than U. Q is not the tallest. S is not the shortest. T is taller than S. P is taller than R but not the 2^nd tallest.

Inference: So, T and U must be the tallest and shortest respectively. As P is not the 2^nd tallest, Q and P must be 2^nd tallest and 3^rd tallest respectively. The arrangement formed is shown below,

T > Q > P > R > S > U

T is the tallest.

Hence, option e.

RBI Assistant 2023 Prelims Free Mock Test

Solution 2: A)

Three persons are shorter than P.

Hence, option a.

Solution 3: E)

Clues: Phone B is heavier than at least three phones. Phone A is lighter than only phone C. Phone D is heavier than phone E and phone F. Neither phone E nor phone F is the lightest.

Inference: So, we have following arrangement,

C > A > D/B > B/D > E/F > F/E > G

Either three or two phones are heavier than phone D.

Hence, option e.

Solution 4: B)

Phone G is the lightest phone.

Hence, option b.

RBI Assistant 2023 Prelims Free Mock Test

Solution 5: B)

Clues:

Only Q and L are taller than M.

N is shorter than O and K.

N is not the shortest person.

Inference:

K is the 3^rd tallest person.

N is the 2^nd shortest person.

P is the shortest person.

Q/L > L/Q > M > K/O > O/K > N > P

Clues:

K is not the 3^rd shortest person.

Q is not the 2^nd tallest person.

Height of 2^nd tallest person is 127cm and height of 3^rd shortest person is 100cm.

Inference:

Q is the tallest person.

L is the 2^nd tallest person.

O is the 3^rd shortest person.

Q > L (127cm) > M > K > O (100cm) > N > P

Height of K is more than 100cm and less than 127cm.

The probable height of K is 121cm.

Hence, option b.

RBI Assistant 2023 Prelims Free Mock Test

Solution 6: D)

N is the 2^nd shortest person.

Hence, option d.

Solution 7: E)

Now, equal number of persons is taller and shorter than D. C is shorter than only B. A and F are taller than E, who is not the shortest. So, G must be the shortest. Therefore, we have following arrangement,

B > C > A/F > D > F/A > E > G

G is the shortest.

Hence, option e.

Solution 8: E)

Either two or four persons are shorter than F.

Hence, option e.

Solution 9: A)

P is heavier than only R which means R is the lightest. T is lighter than Q but heavier than S which means Q is the heaviest. U is heavier than V and lighter than T which means T is the 2^nd heaviest persons among all.

The final arrangement is as follows:

Q(80kg) > T > U(50kg) > V > S > P > R

So, if the sum of the weights of U and R is 90kg which means the weight of R is 40kg and the sum of the weights of V and Q is 125kg which means the weight of V is 45kg so, the difference between the weights of V and R is 5kg(45-40)

Hence, option a.

Solution 10: E)

Both U and T are heavier than V but lighter than Q.

Hence, option e.
