Correct answer

Answer: (b)B.

7

Why this answer is correct

Given 

215 + 369 – 60% of 900 + 5 = ?2

Concept Used 

Follow the BODMAS rule according to the table given below:

Calculation

215 + 369 – 60% of 900 + 5 = ?2

⇒ √(215 + 369 - 540 + 5) = ?

⇒ ? = √(589 - 540) = 7

∴ The required answer is 7

Question 32

Correct answer

Answer: (a)A.

39

Why this answer is correct

Given 

(252 – 106) ÷ 3 – 132 + 35 = ?

Concept used 

Follow the BODMAS rule according to the table given below:

Calculation 

(252 – 106) ÷ 3 – 132 + 35 = ?

⇒ (625 - 106) ÷ 3 - 169 + 35 = ?

⇒ 519 ÷ 3 - 169 + 35 = ? 

⇒ 173 - 169 + 35 = ?

⇒ ? = 39 

∴ the required answer is 39

Mistake Points ⇒ 173 - 169 + 35 = ?

there is no btacket after - sign before 169 so the calculation can't come -204.

Question 33

View answer & explanation

Correct answer

Answer: (c)C.

2

Why this answer is correct

Calculation 

(3.9 + 4.1) × 2.5 + 9 – 25 = ?2

⇒ 8 × 2.5 + 9 - 25 = ?2

⇒ 20 + 9 - 25 = ?2

⇒ ? = √4 = 2  

∴ The required answer is 2

Answer: (d)D.

35

Why this answer is correct

The correct answer is: 4

Given:

377 ÷ 13 + √81 - 57 ÷ 19 = ?

Concept used:

The BODMAS rule should be followed as per the given table:

 

 

Calculation:

377 ÷ 13 + √81 - 57 ÷ 19 = ?

29 + √81 - 3 = ?

29 + 9 - 3 = ?

38 - 3 = ?

⇒ ? = 35

 

∴ The value of '?' is 35

Question 35

View answer & explanation

Correct answer

Answer: (c)C.

20

Why this answer is correct

The correct answer is : 3

Given:

12% of √5625 - ? % of √225 = 142 - 136

Concept used:

The BODMAS rule should be followed as per the given table: 

 

Calculation:

12% of √5625 - ? % of √225 = 142 - 136

⇒ 12/100 × 75  - ?/100  × 15 = 6

⇒ 3/25 × 75  - ?/100  × 15 = 6

⇒ 9 - ?/100  × 15 = 6 

⇒ 3 = ?/100  × 15

⇒ ? = (100×3)/15

⇒ ? = 20

 

∴ The value of '?' is 20

Question 36

  3. COption (c)

    3300

  4. DOption (d)

    3500

  5. EOption (e)

    2800

View answer & explanation

Correct answer

Answer: (a)A.

3200

Why this answer is correct

Given:

48% of 420 + 32% of 470 = 11% of ?

Concept Used:

a% of b = b% of a

Calculation:

Follow the BODMAS rule according to the table given below:

⇒ 48% of 420 + 32% of 470 = 11% of ?

⇒ 48% of 420 + 32% of (420 + 50) = 11% of ?

⇒ 48% of 420 + 32% of 420 + 32% of 50 = 11% of ?

⇒ (48% + 32%) of 420 + 50% of 32 = 11% of ?

⇒ 80% of 420 + 50% of 32 = 11% of ?

⇒ (80/100) × 420 + 1/2 × 32 = (11/100) of ?

⇒ 8 × 42 + 16 = (11/100) of ?

⇒ 336 + 16 = (11/100) of ?

⇒ 352 = (11/100) of ?

? = (352 × 100)/11

⇒ 32 × 100

⇒ 3200

∴ The value of '?' is 3200.

Correct answer

Answer: (b)B.

20

Why this answer is correct

Concept used:

Follow the BODMAS rule according to the table given below:

Calculation:

56 ÷ 14 × 4 – 316 + ?2  = 100

⇒ 4 × 4 – 316 + ?2 = 100

⇒ 16 – 316 + ?2 = 100

⇒ ?2 = 100 + 316 – 16

⇒ ?2 = 416 – 16

⇒ ?2 = 400

⇒ ? = 20

∴ The value of ? is 20

⇒ 75 ÷ 15 × 21 ÷ 3 + 5 = ?

⇒ 5 × 21 ÷ 3 + 5 = ?

⇒ 5 × 7 + 5 = ?

⇒  35 + 5 = ?

⇒ ? = 40

∴ The value of ? is 40

Question 39

LIC ADO 2023• Numerical Ability

Direction: The bar graph given below provides the detail about the total number of watches and the total number of bags sold in three shops P, Q and R. Analyze the data and answer the following questions:

Find the difference between the total number of watches and total number of bags when data from all the bags are considered? 

  1. AOption (a)

    5

  2. BOption (b)

    6

  3. COption (c)

    7

  4. DOption (d)

    8

  5. EOption (e)

    9

View answer & explanation

Correct answer

Answer: (c)C.

7

Why this answer is correct

Total number of bags from all the shops = 40 + 70 + 35 = 145

Total number of watches from all the shops = 60 + 50 + 42 = 152

So the difference between the total number of bags and watches from all the shops is 152 - 145 = 7.

Question 40

LIC ADO 2023• Numerical Ability

Direction: The bar graph given below provides the detail about the total number of watches and the total number of bags sold in three shops P, Q and R. Analyze the data and answer the following questions:

If the ratio of the total number of male and female watches is 10:9 in all the shops and the ratio of the male and female bags is 10:19 in all the shops, find the total number of female items are present in both the shops?

  1. AOption (a)

    113

  2. BOption (b)

    147

  3. COption (c)

    157

  4. DOption (d)

    177

  5. EOption (e)

    167

View answer & explanation

Correct answer

Answer: (e)E.

167

Why this answer is correct

The total number of watches in all the shops = 60 + 50 + 42 = 152

The ratio of male and female watches is 10:9,

Hence the total number of female watches = (9/(10 + 9)) x 152 = 72.

The total number of bags in all the shops = 40 + 70 + 35 = 145

The ratio of male and female bags is 10:19,

Hence the total number of female bags = (19/(10 + 19)) x 145 = 95.

Hence the total number of female items = 72 + 95 = 167.
