    9

Show Answer
Answer: ((b))

6

Given:- Number = 5132832

To find:- Divisibility of a number

Concept used:- Divisibility of 5, 6, 7 and 9

Calculation**:-** As we have to check the number whether it is divisible by 5, 6, 7, or 9 then we have to go by options,

Checking option- 1

Divisibility of 5, 

If the last number is either 0 or 5, the entire number is divisible by 5

Last digit of the given number is 2

Hence the given number is not divisible by 5.

Checking option- 2

Divisibility of 6 states that the number which is divisible by 2 and 3 is also divisible by 6

Since the number is even so it is divisible by 2

For a number to be divisible by 3, the sum of digit must have 3 as a multiple

⇒Sum = 5 +1+ 3 + 2 + 8 + 3 + 2 = 24

24 is divisible by 3 hence the number is also divisible by 3

⇒The number is divisible by 6

Checking option- 3

Divisibility of 7 states that twice the unit digit when subtracted from the remaining part then the outcome must be a multiple of 7

⇒513283 - 4 = 513279

On repeating this several times,

⇒51328 - 6 = 51322

⇒5132 - 4 = 5128

⇒512 - 16 = 496

⇒49 - 12 = 37

Since 37 is not a multiple of 7 hence the number is not divisible by 7

Checking option- 4

Divisibility of 9 states that if the sum of the digits of a number is divisible by 9 then the number is divisible by 9

⇒The sum of digit is 24 which is not divisible by 9 hence the number is not divisible by 9.

.·. The number is divisible by 6.

The sum of two numbers is 140. If their LCM is 240 and HCF is 20, then find the smaller number.

  1. ((a))

    60

  2. ((b))

    140

  3. ((c))

    20

  4. ((d))

    80

Show Answer
Answer: ((a))

60

Shortcut Trick

Let the numbers be 20x and 20y (where x and y are co-prime).

Sum: 20(x + y) = 140 ⇒ x + y = 7

LCM: 20xy = 240 ⇒ xy = 12

Numbers with sum 7 and product 12 are 3 and 4.

Smaller number = 20 × 3 = 60.

∴ The correct answer is 60.

Alternate Method

Given: Sum of numbers (A + B) = 140, LCM = 240, HCF = 20.

Formula Used: Product of two numbers = HCF × LCM

⇒ A × B = 20 × 240 = 4800

⇒ We know (A − B)2 = (A + B)2 − 4AB

⇒ (A − B)2 = (140)2 − 4(4800)

⇒ (A − B)2 = 19600 − 19200 = 400

⇒ A − B = √400 = 20

⇒ Adding (A + B = 140) and (A − B = 20): 2A = 160 ⇒ A = 80

⇒ Subtracting: 2B = 120 ⇒ B = 60

∴ The correct answer is 60.

Additional Information

HCF and LCM Property

For any two numbers a and b, the product of the numbers is always equal to the product of their HCF and LCM: a × b = HCF(a, b) × LCM(a, b).

Co-prime Relationship

If HCF of two numbers is h, then the numbers can be represented as hx and hy, where x and y are co-prime (HCF of x and y is 1).

LCM of Fractions

LCM of fractions = (LCM of numerators) ÷ (HCF of denominators).

Given:

Side (a) of rhombus = 13 cm 

Length of one diagonal (p) = 24 cm 

Formulas used:

a = (p2 + q2 )1/2÷ 2

Area of rhombus = 1/2 × p × q

Calculation:

Let the other diagonal of rhombus = q 

⇒ (242 + q2)1/2 ÷ 2 = 13

⇒ (576 + q2)1/2 = 26

⇒ 576 + q2 = (26)2

⇒ 676 - 576 = q2

⇒ q = √100 = 10 

Area = 1/2 × 24 × 10 = 120 cm2

∴ The correct answer is 120 cm2.

Show Answer
Answer: ((b))

60√3 cm

Given:

Sides of right -angled triangle = 20√ 3 cm and 15√ 3 cm

Formula used:

Hypotenuse2 = Perpendicular2 + Base2

Perimeter of triangle = a + b + c

Calculation:

The height and base of a right angled- triangle be 20√ 3 cm and 15√ 3 cm respectively

For right angled triangle,

Hypotenuse2 = Perpendicular2 + Base2

⇒ Hypotenuse2 = (20√3)2 + (15√3)2

⇒ Hypotenuse2 = (1200) + (675)

⇒ Hypotenuse2 = 1875

⇒ Hypotenuse = 25√3

Perimeter of triangle = (20√3 + 15√3 + 25√3) cm

⇒ 60√3 cm

∴ Perimeter of triangle is 60√3 cm

Show Answer
Answer: ((b))

6 + 233\sqrt {33}

Given:

PA = 10 cm

QA = 14 cm

AB = 16 cm

Concept used:

Pythagoras Theorem 

Distance between two centers divides the common chord into halves and is perpendicular to the common chord as well.

Calculation:

AR = RB = 16 ÷ 2 = 8 cm

AB is perpendicular to PQ. 

Hence, PQ divides AB in halves.

Now,

PR = 102−82\sqrt {10^2 - 8^2} = 6 cm

QR = 142−82\sqrt {14^2 - 8^2 } = 2√33 cm

Thus, PQ = (6 + 2√33) cm

∴ The distance between their centres is (6 + 2√33) cm.

Show Answer
Answer: ((c))

133513\frac{3}{5}

Given:

Amount = Rs. 1500

Rate = 2% and Time = 3 years

Concept used:

SI = (P × R × T)/100

A = P + SI

SI = A - P

T = SI×100P×R\frac{SI × 100}{{P × R}}

Where, P = Principal, R = Rate of interest, 

T = Time period, A = Amount, SI = Simple interest

Calculation:

According to the above concept,

A = P + SI

Initial amount = 1500/-, Principal

⇒ A = P + (P × R × T)/100

⇒ P(1 + R×T100\frac{R × T}{{100}}) = 1500    

⇒ P(1 + 2×3100\frac{2 × 3}{{100}}) = 1500

⇒ P(1 + 6100\frac{6}{{100}}) = 1500

⇒ P(1 + 350\frac{3}{{50}}) = 1500

⇒ P × 5350\frac{53}{{50}} = 1500

⇒ 53P50\frac{53P}{{50}} = 1500

⇒ P = 7500053\frac{75000}{{53}}

Now, Final amount = 1800, Principal remains same

SI = Final amount - Principal 

⇒ SI = 1800 - 7500053\frac{75000}{{53}}

⇒ SI = (95400−7500053\frac{95400-75000}{{53}})

⇒ SI = 2040053\frac{20400}{{53}}

Now, T = SI×100P×R\frac{SI × 100}{{P × R}}

⇒ T = 20400×100×5353×75000×2\frac{20400 × 100\times 53}{{53 × 75000 \times 2}}

⇒ T = 685\frac{68}{{5}} = 133513\frac{3}{5}

Answer: ((a))

7127\frac{1}{2}

Given:

Time taken by A to do the work = 15 days

Time taken by B to do the work = 30 days

B did that work for 5 days and he left the work.

Concept used:

Work = Efficiency × Time

Calculation:

LCM of 15 and 30 is 30

Efficiency of A = (3015\frac{30}{{15}}) = 2 units/day

Efficiency of B = (3030\frac{30}{{30}}) = 1 unit/day

Now, according to the question

A and B work together for 5 days, then B left = [5 × (2 + 1)] units 

⇒ (5 × 3) = 15 units

Remaining work = (30 - 15) units = 15 units

Now, the remaining work completed by A = (152\frac{15}{{2}}) = 7127\frac{1}{2} days

∴ The required time is 7127\frac{1}{2} days.

Calculation:

Let the age of his Uncle be U years and Rahim be R years.

Now, according to the question

⇒ U - R = 10      -----(1)

After 2 years, the sum of their ages = 66 years

Age of Uncle after 2 years = (U + 2) years

Age of Rahim after 2 years = (R + 2) years

Their sum = (U + 2 + R + 2) = 66

⇒ U + R + 4 = 66

⇒ U + R = 62        ------(2)

Now, adding equations (1) and (2), we get

⇒ 2U = 72

⇒ U = 36 years

∴ The required age of his uncle is 36 years.

Shortcut Trick

Assume all 77 animals are goats (4 legs each).

Total legs = 77 × 4 = 308.

Difference in legs = 308 − 248 = 60.

Difference in legs per animal (Goat − Hen) = 4 − 2 = 2.

Number of hens = 60 ÷ 2 = 30.

∴ The correct answer is 30.

Alternate Method

Given:

Total heads = 77 | Total legs = 248

Let the number of hens be H and goats be G.

⇒ H + G = 77 --- (i)

⇒ 2H + 4G = 248 --- (ii)

Multiply equation (i) by 4:

⇒ 4H + 4G = 308 --- (iii)

Subtract equation (ii) from (iii):

⇒ (4H − 2H) + (4G − 4G) = 308 − 248

⇒ 2H = 60

⇒ H = 30

∴ The correct answer is 30.

Additional Information

Five years ago, the average age of A,B,C and D was 45 years. By including X in the present lot their present average changes to 49 years. What is the present age of X?

  1. ((a))

    40 years

  2. ((b))

    45 years

  3. ((c))

    49 years

  4. ((d))

    48 years

Show Answer
Answer: ((b))

45 years

Calculation:

Five years ago, the average age of A,B,C and D was 45 years

⇒ Present average age of them = (45 + 5) = 50 years

Sum of present age of A, B, C and D = 50 × 4 = 200 years

Present average age of A, B, C, D and X is 49

⇒ Sum of present age of A, B, C, D and X is (49 × 5) = 245 years

Present age of X is (245 - 200) = 45 years

∴ The present age of X is  45 years.

    3:1

  3. ((c))

    3:4

  4. ((d))

    1:3

Show Answer
Answer: ((b))

3:1

Given:

The ratio of the areas of two squares = 9 : 1

Concept used:

Area of square = a2

Perimeter of square = 4a

Calculation:

Let the area of square be A1 and A2 respectively

Now, according to the question

Areaofsquare(A1)Areaofsquare(A2)\frac{Area of square(A_1)}{{Area of square(A_2)}}  = a12a22\frac{a_1^2}{{a_2^2}} = 91\frac{9}{{1}}

⇒ a1a2\frac{a_1}{{a_2}}= √(91\frac{9}{{1}})

⇒ a1a2\frac{a_1}{{a_2}}= 31\frac{3}{{1}}

Now, Perimeter of square is

⇒ Perimeterofsquare(1)Perimeterofsquare(2)\frac{Perimeter of square(1)}{{Perimeter of square(2)}}  = 4a14a2\frac{4a_1}{{4a_2}} 

⇒ (44\frac{4}{{4}} × 31\frac{3}{{1}}) = 31\frac{3}{{1}}

∴ The required ratio of their perimeters is 3 : 1.

  1. No K are B → Follow: Since no S is B and all K are S. Thus, no K are B is true.

  2. Some T are not S → Follow: Since no S is B and some B are T. Thus, some T are not S is true.

  3. Some T are B → Follow: Since some B are T and so some T are B is true.

  4. All B being K is a possibility → Unfollow: Since no S is B and all K is S. Thus, all B being K is not possible. This is not true.

Thus, only 4 does not follow.

Hence, the correct answer is 'option 4'.

    The shark

  2. ((b))

    deep into the sea

  3. ((c))

    attacked the swimmer

  4. ((d))

    when he go

Show Answer
Answer: ((d))

when he go

The correct answer is “when he go”

Key Points

  • The part of the sentence that has an error is "when he go." 
  • The correct form is "when he went," which is the past tense of the verb "go."
  • "When he go" is the subordinating conjunction and the verb, which is in the present tense. This is incorrect, as the sentence is in the past tense, and the verb should be in the past tense as well.
  • "The shark" is the subject of the sentence and is grammatically correct.
  • "Deep into the sea" is a prepositional phrase that functions as an adverbial phrase to describe where the swimmer went, and it is grammatically correct.
  • "Attacked the swimmer" is the main verb of the sentence and is grammatically correct.

Hence, the correct answer is “The shark attacked the swimmer when he went deep into the sea.”

  • The verb pursues after the model verb can does not appear to be in the correct form.

Therefore, the correct sentence is- "The greatest merit of democracy is that everyone feels free and can pursue his/her interest."

  3. ((c))

  4. ((d))

    business deals

Show Answer
Answer: ((a))

sooner then

The correct option is 'sooner then'.

Key Points

  • ​The correct answer is 1) sooner then. The correct word should be "than" instead of "then". The correct sentence is: She would resign sooner than take part in such dishonest business deals.
  • "Sooner" is a comparative adverb, meaning it is used to compare two actions or events in terms of time. The correct comparative form of "soon" is "sooner than," not "sooner then."

"Then" and "than" are two commonly confused words in English language.

  • "Then" is an adverb which is used to indicate time or sequence, such as "We went to the store, and then we went to the park". It can also be used to indicate a consequence, such as "If you study hard, then you will pass the exam".
  • On the other hand, "than" is a conjunction which is used to make comparisons between two things, such as "She is taller than him". It can also be used to indicate preference, such as "I would rather stay home than go out tonight".
  • In the given sentence "She would resign sooner then take part in such dishonest business deals", the correct word to use is "than" instead of "then", as the sentence is making a comparison between resigning and taking part in dishonest business deals. So, the error is in option 1, "sooner then". It should be "sooner than". The correct sentence would be "She would resign sooner than take part in such dishonest business deals".

than either

The correct answer is 'than either'.

Key Point

  • The expression ‘either of ’ means any one of the two
  • Whereas in the given sentence it has been clearly mentioned that subject is more than 2 entities/subjects
  • Thus distributive pronoun to be used in the given sentence will be 'each of '
  • Each of - 'Each of' is used with plural nouns which means we are referring to more than one individual in a group
  • For e.g.- Each of the five candidates received a present.
  • Thus to make the sentence correct than either will be replaced by 'than each'

​Correct sentence- She was taller than each of her five sisters.
