**Study the data given in the caselet below and answer the questions 63-64 that follow:**

In an innings of a T20 cricket match (a team can bowl for 20 overs) 6 bowlers bowled from the fielding side, with a bowler allowed maximum of 4 overs. Only the three specialist bowlers bowled their full quota of 4 overs each, and the remaining 8 overs were shared among three non-specialist bowlers. The economy rates of four bowlers were 6, 6, 7 and 9 respectively. (Economy rate is the total number of runs conceded by a bowler divided by the number of overs bowled by that bowler). This however, does not include the data of the best bowler (lowest economy rate) and the worst bowler (highest economy rate). The number of overs bowled and the economy rate of any bowler are in integers.

**63.** Read the two statements below:

S1: The worst bowler did not bowl the minimum number of overs.

S2: The best bowler is a specialist bowler.

Which of the above statements or their combinations can help arrive at the minimum number of overs bowled by a non-specialist bowler?

(1) S1 only.

(2) S2 only.

(3) Either S1 or S2.

(4) S1 and S2 in combination.

(5) The minimum number of overs can be determined without using S1 or S2.

**64.** Read the two statements below:

S1. The economy rates of the specialist bowlers are lower than that of the non-specialist bowlers.

S2. The cumulative runs conceded by the three non-specialist bowlers were 1 more than those conceded by the three specialist bowlers.

Which of the above statements or their combinations can help arrive at the economy rate of the worst bowler?

(1) S1 only.

(2) S2 only.

(3) Either S1 or S2.

(4) S1 and S2 in combination.

(5) The economy rate can be calculated without using S1 or S2.

**Analyse the graph below and answer the questions 65-68 that follow:**

The grid below captures relationships among seven personality dimensions: "extraversion", "true_arousal_plac", "true_arousal_caff”, "arousal_plac", "arousal_caff”, "performance_plac", and "performance caff”. The diagonal represents histograms of the seven dimensions. Left of the diagonal represents scatterplots between the dimensions while the right of the diagonal represents quantitative relationships between the dimensions. The lines in the scatterplots are closest approximation of the points. The value of the relationships to the right of the diagonal can vary from -1 to +1, with -1 being the extreme linear negative relation and +1 extreme linear positive relation. (Axes of the graph are conventionally drawn).

(1) "Extraversion" has two modes.

(2) Median for "arousal_plac" is definitely the same as its average.

(3) Median for "arousal_caff" is definitely higher than its average.

(4) Median for "performance_plac" is definitely lower than its average.

(5) Median for "performance_caff" is definitely lower than its average.

**66. Which of the scatterplots shows the weakest relationship?**

(1) Between "extraversion" and "performance_caff".

(2) Between "true_arousal_plac" and "arousal_plac".

(3) Between "true_arousal_plac" and "performance_plac".

(4) Between "true_arousal_caff" and "performance_caff".

(5) Between "arousal_caff" and "performance_caff".

(2) "true_arousal_plac" and “arousal_plac"

(3) "true_arousal_plac" and "performance_plac"

(4) "true_arousal_plac" and "performancc_caff"

(5) All the above are irrelevant relations.

**68. Which of the following options is correct?**

(1) 0.93 on the right side of the diagonal corresponds to the third scatterplot in the fourth row.

(2) 0.94 on the right side of the diagonal corresponds to the second scatterplot in the fourth row.

(3) 0.38 is the relationship between "extraversion" and "true_arousal_plac".

(4) "arousal_catr” and "performance_caff" arc positively related.

**Study the paragraph below and answer the questions 69-72 that follow:**

Abdul has 8 factories, with different capacities, producing boutique kurtas. In the production process, he incurs raw material cost, selling cost (for packaging and transportation) and labour cost. These costs per kurta vary across factories. In all these factories, a worker takes 2 hours to produce a kurta. Profit per kurta is calculated by deducting raw material cost, selling cost and labour cost from the selling price (Profit = selling price - raw materials cost - selling cost - labour cost). Any other cost can be ignored.
