• The given sentence is in the active voice and it is in the present simple tense.
• When we convert this sentence into a passive voice, the subject 'Anant' of the active voice becomes the object, the object 'experimenting with different cuisines' becomes the subject.

• ''Mine'' comes at the end of a dialogue. The noun comes before ''mine''.
• For example, That black and brown clock is mine.

• ''My'' comes before a noun or object (here, gratitude) in a sentence. It is followed by a noun (here, gratitude).

Hence, the correct answer is option 3.

Correct sentence: I have made it a point to call my teachers on September 5 as a token of my gratitude.

• उदाहरण: My clock is black and brown.
• इसलिए, pronoun 'mine' के स्थान पर pronoun 'my' का प्रयोग करना चाहिए।

Let the cost of fuel as 100 rupees/ litre and customer refills only 100 rupees fuel, no matter the increase or decrease in price.

Now if the cost is increased to 20% it will be

= 100 + (20 × 100) ÷ 100

= 100 + 20

= 120 rupees/ litre

So the price difference is 120 – 100 = 20 rupees/ litre

Now if the expenditure should be same so that customer will pay only 100 rupees, then he must be consuming less fuel. ( i.e lesser than 1 litre.). So he will consume:-

i.e (100 rupees ÷ 120 rupees) × 1 litre= ${5 \ \over 6}$ litre.

Reduction in quantity of fuel consumed by customer = 1 litre – ${5 \ \over 6}$ litre= ${1 \ \over 6}$ litre.

Therefore percentage reduction of fuel consumption by customer = ${100 \ \over 6}$ % = ${50 \ \over 3}$ % = $16\frac{2}{3}\%$

Hence, "option 2" is the correct answer.

Given:

Number = 9685

(1/4) first part = (1/3) second part = (1/6) third part

Shortcut TrickThe first number is divisible by 4 according to the question.

The option which is divisible by 4 will be the answer.

From the given options, we can see, only 2980 among

the options are divisible by 4.

∴ First part of the number is 2980. 

<br>

Alternate Method

Let first part, second part, and third part be a, b and c respectively.

⇒ a/4 = b/3 = c/6 = k

⇒ a = 4k, b = 3k and c = 6k

⇒ a + b + c = 9685

⇒ 4k + 3k + 6k = 9685

⇒ k = 745

First part = a = 745 × 4 = 2980

∴ The first part of the number is 2980.

Given:

(7x + 3)3 + (x - 2)3 + 27(2x - 5)3 = 9(7x + 3) × (x - 2) × (2x - 5)

Formula:

When,

⇒ a + b + c = 0

then,

⇒ a³ + b³ + c³ = 3abc or vice versa

Calculation:

⇒ (7x + 3)³ + (x - 2)³ + 3³(2x - 5)³ = 3 × (7x + 3) × (x - 2) × 3(2x - 5)

a = 7x + 3, b = x - 2 and c = 3(2x - 5)

Then,

⇒ (7x + 3) + (x - 2) + 3(2x - 5) = 0

⇒ 7x + 3 + x - 2 + 6x - 15 = 0

⇒ 14x - 14 = 0

⇒ x = 1

Then,

⇒ 5x + 3 = 5 × 1 + 3 = 8

∴ 5x + 3 = 8

Given:

Two discounts = 40% and 20%

Formula:

Two discounts a% and b%

Total discount = $(a +b)- \frac{ab}{100}$

Discount amount = (marked price) × (discount %)/100

Calculation:

Single discount percentage = $(40 +20)- \frac{40× 20}{100}$ = 52%

⇒ 52 = 988/marked price × 100

⇒ Marked price = 1900

∴ Marked price of an article is Rs.1900.

Alternate MethodLet the MP be x.

x - [x × (100 - 40)/100 × (100 - 20)/100] = 988

⇒ x - [x × (60/100) × (80/100)] = 988

⇒ x - x × (3/5) × (4/5) = 988

⇒ 13x/25 = 988

⇒ x = (988 × 25)/13

⇒ x = 1900

∴ Marked price of an article is Rs.1900.

Given:

⇒ x + y = 5 

⇒ x2 + y2 = 17

Formula:

⇒ (a + b)² = a² + b² + 2ab

⇒ (a - b)2 = a2 + b2 - 2ab

Calculation:

⇒ (x + y)² = x² + y² + 2xy

⇒ 2xy = 25 - 17 = 8

Then,

(x - y)² = x² + y² - 2xy 

= 17 - 8  

= 9

∴ (x - y)2 = 9

Shortcut TrickPut x = 4 and y = 1, it satisfies the condition given in the question.

(x - y)2 = (4 - 1)²

⇒ 9

∴ (x - y)2 = 9

Given:

∠ACB = 66º and ∠ABC = 44º

Calculation:

∠ABC + ∠CBD = 180    ....(Linear angles)

∠CBD = 180º - 44º = 136º

Using angle bisector,

∠CBI = ∠IBD = 136º/2 = 68º

∠ACB + ∠BCE = 180º   ....(Linear angles)

∠BCE = 180º - 66º = 114º

Using angle bisector,

∠BCI = ∠ICE = 114º/2

∠BCI = 57º

In ΔBCI,

∠BCI + ∠CBI + ∠BIC = 180º

∠BIC = 180º - 68º - 57º = 55º

∴ ∠BIC = 55º

Alternate Method∠A = 180° - (44° + 66°)

⇒ ∠A = 70° 

∠BIC = 90 - ∠A/2 (Exterior angle bisector)

∠BIC = 90 - 70/2

⇒ 90 - 35 = 55° 

∴ ∠BIC = 55º

Calculation:

Total qualified students from districts B = 68000 × 25/100 = 17000

Total qualified students from districts C = 68000 × 28/100 = 19040

Number of students from districts B above 22 years old = 17000 × 78/100 = 13260

Number of students from districts C above 22 yearls old = 19040 × 80/100 = 15232

∴ Require percentage = 13260/15232 × 100 = 87.05%

Alternate MethodWe do not need the real number to calculate it.

From District B, the number of students above 22 years old

⇒ 78% of 25%

From district C, the number of students above 22 years old

⇒ 80% of 28%

The required percentage = 

[(78 × 25)/(80 × 28)] × 100

⇒ ≈ 87%

Given:

Total number of vehicles of company A for years 2010, 2012, 2014 and 2015 = 260 + 224 + 266 + 348 = 1098 thousands

Average number of vehicles of company A for years 2010, 2012, 2014 and 2015 = 1098/4 = 274.5 thousands

Total number of vehicles of company B for years 2010, 2012, 2014 and 2015 = 307 + 250 + 310 + 416 = 1283 thousands

Average number of vehicles of company B for years 2010, 2012, 2014 and 2015 = 1283/4 = 320.75 thousands

∴ Required difference = 320.75 - 274.5 = 46.25 thousands

Alternate MethodThe sum of the difference of all years 

⇒ (307 - 260) + (250 - 224) + (310 - 266) + (416 - 348)

⇒ 47 + 26 + 44 + 68

⇒ 185

The average of the difference = 185/4 = 46.25

∴ Required difference = 320.75 - 274.5 = 46.25 thousands

Given:

When an integer n is divided by 6, the remainder is 5

Formula:

Number = quotient × Divisor + remainder

Calculation:

n = quotient × 6 + 5

= 9 × 6 × quotient + 5 × 9

= 9 × 6 × quotient + 7 × 6 + 3

= 6(9quotient + 7) + 3

∴ 3 is the remainder if 9n is divided by 6.

Alternate MethodLet the integer be (6 + 5) = 11

Now, 9n = 9 × 11 = 99

When we divide 99 by 6 we get 16 as quotient and 3 as remainder.

∴ 3 is the remainder if 9n is divided by 6.

Given:

?  = $\frac{{\left[ {\frac{1}{9} \div \frac{1}{9}of\frac{1}{9}} \right] × \frac{1}{9}}}{{\frac{1}{9} + \frac{1}{9}of\frac{1}{9}}}$

Concept:

Calculation:

⇒ ? = $\frac{{\left[ {\frac{1}{9} \div \frac{1}{9}of\frac{1}{9}} \right] × \frac{1}{9}}}{{\frac{1}{9} + \frac{1}{9}of\frac{1}{9}}}$

⇒ ? = [[1/9 ÷ 1/81] × 1/9]/[1/9 + 1/9 × 1/9]

⇒ ? = [9 × 1/9]/[1/9 + 1/81]

⇒ ? = [1]/[10/81]

⇒ ? = 81/10

∴ ? = $8\frac{1}{{10}}$

Given:

(3p - 5m) = 5 and pm = 6

Formula:

⇒ (a - b)² = a² + b² - 2ab

⇒ (a² - b²) = (a - b)(a + b)

⇒ (a + b)2 = (a - b)² + 4ab

Calculation:

⇒ (3p + 5m)² = (3p - 5m)² + 4 × 3p × 5m

⇒ 25 + 60 × 6

⇒ (3p + 5m) = ±√385

∴ (9p2 - 25m²) = (3p - 5m)(3p + 5m) = ±5√385

Given:

SI for 9 years = 45% of P

Formula:

Let P = Principal, R = rate of interest and N = time period

SI = PNR/100

Calculation:

⇒ SI = P × R × 9/100

⇒ 9PR/100 = 45P/100

⇒ R = 5

∴ Rate of interest is 5%.

Alternate MethodTopper's approach -

45% amount increases in 9 years.

5% amount increases in 1 year.

∴ Rate of interest is 5%.

Given:

sin²x - 4 sin x + 3 = 0

Calculation:

Let sinx = k

⇒ k² - 4k + 3 = 0

⇒ k² - 3k - k + 3 = 0

⇒ k(k - 3) - 1(k - 3) = 0

⇒ (k - 1)(k - 3) = 0

k = 1 or k = 3

Then,

⇒ sin x = 1

⇒ x = sin ^-1(1)

∴ x = π/2

Given:

Distance = 844m

Speed of cyclists = 12m/s and 8m/s

Formula Used:

Relative Speed = Speed of faster cyclist - speed of slower cyclist

Calculation:

Relative speed of two cyclists = 12 - 8 = 4 m/s

⇒ Time after which they will overtake = 844/4

⇒ 211 sec

⇒ 3 min and 31 sec

∴ The time taken by P to overtake Q is 3 min 31 sec.

Given:

Average expenditure for first three months = Rs.2400

Average expenditure for five months = Rs.3500

Average expenditure for four months = Rs.4800

Formula:

Average = (Sum of terms)/Number of terms

Calculation:

Total expenditure for first three months = 2400 × 3 = Rs.7200

Total expenditure for five months = 3500 × 5 = Rs.17500

Total expenditure for four months = 4800 × 4 = Rs.19200

Total expenditure in a year = 7200 + 17500 + 19200 = Rs.43900

Total income in a year = 439000 + 3500 = Rs.47400

∴ Average monthly income = 47400/12 = Rs.3950

Alternate MethodTo ease the calculation, let the average expenditure per month be Rs. 3500.

Deflection in the expenditure for first 3 months

⇒ (2400 - 3500) × 3 = -3300

Deflection in the expenditure for the next 5 months be zero.

Deflection in the expenditure for the last four months.

⇒ (4800 - 3500) × 4 = 5200

The total deflection = 5200 - 3300 = 1900

Correct expenditure for 12 months = 3500 × 12 + 1900

Total income for 12 months = 42000 + 1900 + 3500(savings)

⇒ 47400

The average salary = 47400/12 = Rs. 3950

Calculation:

Total number of students in graduate level in institute S = 12400 × 20/100 = 2480

Total number of students in post graduate level in institute S = 8000 × 18/100 = 1440

∴ Required % = (2480 - 1440)/1440 × 100 = 72.2%

Given:

SP = Rs.8670

Loss% = 15%

Formula:

Profit % = (SP - CP)/CP × 100

Loss % = (CP - SP)/CP × 100

Calculation:

⇒ 15 = (CP - 8670)/CP × 100

⇒ CP = Rs.10200

Then,

⇒ 15 = (SP - 10200)/10200 × 100

 ⇒ SP = 11730

∴ Selling price is Rs.11730 when profit % is 15%.

 Alternate Method(100 - 15)% = 8670

⇒ 85% = 8670

⇒ 1% = 8670/85

SP on 15% profit = 115 × (8670/85)

⇒ Rs. 11730

∴ Selling price is Rs.11730 when profit % is 15%.

Calculation:

Total number of vehicles manufactured by company B during 2011 to 2014 = 270 + 250 + 289 + 310 = 1119 thousand

The average number of vehicles manufactured by company B during 2011 to 2014 = 1119/4 = 279.75 thousand

Number of vehicles manufactured by company A in 2009 = 279.75 × 100/(100 + 24) = 225.60 thousand

∴ number of vehicles manufactured by company A in 2009 is 225.60 thousand

Given:

tan θ = 15

Formula:

tan² θ + 1 = sec² θ 

Calculation:

⇒ sec² θ = 225 + 1

∴ sec θ = √226

Given:

$? = \frac{{ta{n^2}{{60}^0} - 2si{n^2}{{45}^0}}}{{cos{{24}^0}cos{{37}^0}coses{{53}^0}cos{{60}^0}cosec{{66}^0} + si{n^2}{{60}^0}}}$

Formula:

cosec(90 - a) = sec a

Calculation:

First solve denominator,

cosec 66º = cosec (90º - 24º) = sec 24º

cosec 53º = cosec (90º - 37º) = sec 37º

Then,

= cos24º.cos37º.cosec53º.cos60º.cosec66º + sin²60º

= cos24º.cos37º.sec37º.sec24º.cos60º + sin²60º

= cos60º + sin²60º

= 1/2 + 3/4

= 5/4

Numerator,

= tan²60º - 2sin²45º

= 3 - 1

= 2

Then,

⇒ ? = 2/(5/4)

⇒ ? = 8/5

∴ [(tan260º - 2sin245º)/(cos24º.cos37º.cosec53º.cos60º.cosec66º + sin260º)] = $1\frac{3}{{5}}$

Calculation:

Let number be N.

⇒ N × 7/5 = 7N/5

⇒ N × 3/2 = 3N/2

∴ % change in result = (3N/2 - 7N/5)/3N/2 × 100 = 6.6667% = $6\frac{2}{3}\%$

Shortcut TrickLet the no. be = 10

Incorrect value = 10 × 7/5 = 14

Correct value = 10 × 3/2 = 15

Ratio of correct to incorrect = 15 : 14

% change = 1/15 = $6\frac{2}{3}\%$

Given:

A's 1 day's work = 1/7

B's 1 day's work = 1/12

Calculation:

(A + B)'s 1 day's work = 1/7 + 1/12 = 19/84

(A + B)'s 3 days work = 3 × 19/84 = 19/28

Remaining work = 1 - 19/28 = 9/28

Number of days in which C alone can complete work = 28/9 × 9 = 28 days

∴ C alone can complete work in 28 days. 

Alternate MethodLet the total work be 84.(LCM of 7 and 12)

Efficiency of A = 84/7 = 12

Efficiency of B = 84/12 = 7

The work of A + B in 3 days = 19 × 3 = 57

Remaining work = 84 - 57 = 27

Efficiency of C = 27/9 = 3

Time required for C = 84/3 = 28 days

Given:

Sum of radii = 286cm

Area of concentric circles = 50336 cm²

Formula:

Area of circle = πr²

Calculation:

Let area of bigger circle and smaller circle be R cm and r cm respectively.

⇒ πR² - πr² = 50336

⇒ R² - r² = 16016

⇒ (R - r)(R + r) = 16016

⇒ (R - r) = 56

 (R + r) = 286

Solving,

R = 171 cm and r = 115cm

∴ Radius of smaller circle and bigger circle is 115cm and 171cm respectively.

Given:

Diameter of a circle = 5.6m

Formula:

Circumference of a semicircle = πr + 2r

Calculation:

Radius of semicircle = 5.6/2 = 2.8 m

Circumference of a semicircle = 22/7 × 2.8 + 2 × 2.8 = 14.4 m

∴ Perimeter of a semicircle = 14.4 m

Given:

Perimeter of isosceles triangle = 3.6m

Formula:

a = equal side and b = unequal side

Area of isosceles triangle = b/2 × √(a² - b²/4)

Calculation:

⇒ b = a - 0.3

⇒ 3.6 = 2a + b

⇒ 3.6 = 2a + a - 0.3

⇒ a = 1.3 m

b = 1.3 - 0.3 = 1m

h = √(a² - b²/4) = √(1.3² - 1²/4) = 1.2 m

Area of triangle = bh/2

Area of isosceles triangle = 1/2 × 1 × 1.2 = 0.6 m²

∴ Area of an isosceles triangle is 0.6 m²

Given:

Dimensions of box = 28 × 4 × 10

Formula:

Diagonal of cuboid = √(l² + b² + h²)

Calculation:

Diagonal of given cuboid box = √(28² + 4² + 10²) = √(784 + 16 + 100) = √(800 + 100) = √(900) = 30cm

∴ the length of the longest rod that can be fitted in a box dimensions 28 cm × 4 cm × 10 cm is 30cm.

The correct answer is Sunlight.
