Andhra Pradesh Public Service Commission (APPSC) released the notification for Group 2 and held the prelims exam in February 2024.

This test includes a section on Mental Ability (Total 30 bits and 30 marks), which is divided into subsections that might include reasoning and arithmetic.

Here we provide fully solved APPSC Group-2 prelims previous paper mental ability questions and also suggest the best scoring material for this topic. Let's follow this matter.

## Reasoning:

(121). Study the following arrangement carefully : **DE*9E$P#6+U0$H1A2D&#AS2ΩA3DS9ALM#**.

What Should be in the place of the question mark (?) in the following sequence based on the above arrangement ? DE* 9$P 60$ A#A ? - AAL

(122). Rajesh codes the alphabets as numbers such as a=l, b=2, and so on. Then what is the value that Rajesh gets by adding all the letters (according to the code given to that letter) in the word **'pneumonoultramicroscopicsilicovolcanoconiosis'** - 560

**Solution:** The word **"pneumonoultramicroscopicsilicovolcanoconiosis"** can be divided into smaller, recognizable segments look like this:

**pneumono(related to lungs or air)-ultra(beyond or extreme)-micro(small)-scopic(related to viewing or observing)-silico(silicon (chemical element))-volcano(volcanic or related to volcanoes)-coniosis(a condition caused by inhaling dust)**. The answer is 560 after summing the alphabetical values for each segment.

Study the given information and answer the following questions: On the occasion of the unveiling of the Statue of Social Justice, the Government of Andhra Pradesh had set up an exhibition and stalls at PWD grounds, Vijayawada.

Raghu went to the exhibition to visit 8 stalls, Stall-1, Stall-2, Stall-3, Stall-4, Stall-5, Stall-6, Stall-7, Stall-8, but not necessarily in the same order.

After visiting Stall-2, he walked 40m in the East direction and reached Stall-7. He then walked 50 m left to reach Stall-8 and then 16 m right to reach Stall-4 and to reach the last stall, he walked 35 m towards the right.

where A, B, C, D, E, F and G are different digits, what is the value of F x G ? - 6.

(139). Some equations are solved on the basis of a certain rule. Following the same rule find out the missing number ?

**2 [4] 3 =14, 4 [6] 5, =32, 5 [7] 6 =44, 6 [8] 7 =?** - 58

(142). Read the following instructions:

(143). Find out the odd one in the following series :

**2, 4, 7, 11.5, 18.25, 28.375, 42.6625** - 42.5625

**Solution:** To find the odd one out in this series, let's analyze the pattern:

- 2 -> 4 (2 + 2 = 4)
- 4 -> 7 (4 + 3 = 7)
- 7 -> 11.5 (7 + 4.5 = 11.5)
- 11.5 -> 18.25 (11.5 + 6.75 = 18.25)
- 18.25 -> 28.375 (18.25 + 10.125 = 28.375)
- 28.375 -> 42.5625 (28.375 + 14.1875 = 42.5625)

The correct next number should be 42.5625, not 42.6625 as given in the original series.

The pattern is that each new number is obtained by adding 1.5 times the previous increase:

2 -> 3 -> 4.5 -> 6.75 -> 10.125 -> 14.1875

42.6625 breaks this pattern, making it the odd one out.

## Arithmetic

(128). The speeds of Rohit and Lalith are 30 km/h and 40 km/h. Initially, Lalith is at place X and Rohit is at place Y. The distance between X and Y is 650 kms.

Rohit started his journey 3 hours earlier than Lalith to meet him. If they both meet each other at a place Z somewhere between X and Y and the distance between Y and Z is P, then what is the value of P+2? - 165

(131). In the month of January, the students of Chaitanya Bharathi Public School visited M/S Swaminathan Farm, where they saw rabbits and pigeons.

One Student started counting. If the heads are counted; there are 340 heads and if the legs are counted there are 1060 1egs.

(132). The Sum of the present ages Of Ramu and his son jagadeesh is 60 years. Six years ago, Ramu's age was five times the age of Jagadeesh. After 6 years, Jagadeesh's age Will be : 20 Years

**Solution:** Given information:

- The sum of the present ages of Ramu and Jagadeesh is 60 years.
- Six years ago, Ramu's age was five times the age of Jagadeesh.

**Step 1:** Let's represent Ramu's and Jagadeesh's ages.

- Let Ramu's present age be x years.
- Then, Jagadeesh's present age is (60 - x) years.

**Step 2:** Six years ago, Ramu's age was five times the age of Jagadeesh.

- Ramu's age six years ago = x - 6 years
- Jagadeesh's age six years ago = (60 - x) - 6 years = (54 - x) years

Since Ramu's age was five times the age of Jagadeesh six years ago, we can write:

(x - 6) = 5 × (54 - x), then after solving x = 46

**Step 3:** Calculate Jagadeesh's present age.

Jagadeesh's present age = 60 - x = 60 - 46 = 14 years

**Step 4:** Calculate Jagadeesh's age after 6 years.

Jagadeesh's age after 6 years = 14 + 6 = 20 years, so the answer is 20 years.

However, If you want to solve most problems quickly, you should refer to the book 'Quicker Maths'.
