The correct answer is 6.50%.

Key Points

• As per the Macro-Economic Framework Statement 2020-21, milk production in India grew 6.50% in 2018-19 over the previous year.
• India has transformed from a country of acute milk shortage to the world’s leading milk producer.
• This phenomenal success is attributed to a Government initiative known as Operation Flood (1970–1996) and its intense focus on dairy development activities.
• Production of milk is subject to seasonal fluctuations — animals, particularly buffaloes, produce more during winter spring and less in the summer.
• In order to cope with this fluctuation, the farmers usually convert the surplus milk of the “flush” season (winter) into skimmed milk powder (SMP) and ghee/butter for reconstitution in the “lean” months (summer).
• Dairy is currently the top-ranking commodity in India, with the value of output almost equal to the combined output value of rice and wheat.
• Despite the importance of the dairy sector in overall GDP, it receives less government budgeting than the agriculture sector.

Additional Information

• Short-Term Measure :
• The government should consider the temporary procurement of milk, directly by the National Dairy Development Board (NDDB).
• NDDB may create a buffer stock of processed dairy products like skimmed milk powder (SMP) and butter.
• Also, state governments may consider distributing these dairy products in Mid-May Meal, when schools reopen.
• In this way, the crisis in the dairy sector and nutritional security both can be addressed.
• Long-Term Measures :
• Increasing Productivity: There is a need to increase the productivity of animals, better health care and breeding facilities and management of dairy animals. This can reduce the cost of milk production.
• Also, milk production and productivity can be enhanced by ensuring the availability of veterinary services, artificial insemination (AI), feed and farmer education.
• The Government and dairy industry can play a vital role in this direction.

S.I. = simple interest

R = rate%

P = principal sum

Given:

C.I. - S.I. = 732

Rate = 10%

Time = 2 years

Calculation:

732 = P ( $10 ×10 \over 100 × 100$)

732 = P/100

P = 73200

Hence, 73200 is the correct answer.

The pattern followed here is:

squaring the 1st number then add 3 to it, we get the 2nd number.

Multiply the 2nd number with 2 then add 3 to it, we get the 3rd number.

$4^2 + 3$

= 16 + 3

= 19

and 19 × 2 + 3

= 38 + 3

= 41

Only option 1 follows this pattern.

$8^2 + 3$

= 64 + 3

Given equation : 176 - 16 + 33 × 6 ÷ 200 = 9

Checking with the options

option 1) + and ÷

176 - 16 ÷ 33 × 6 + 200

= 176 - 0.48 × 6 + 200

= 373.12

option 2) - and ÷

176 ÷ 16 + 33 × 6 - 200

= 11 + 198 - 200

= 9

option 3) ÷ and ×

176 - 16 + 33 ÷ 6 × 200

= 176 - 16 + 5.5 × 200

Hence, the correct answer is - and ÷ .

When the question figure is merged with the figure in option 3, the complete pattern can be seen as:

Hence, the figure in option (3) is the correct answer.

Given:

Rate of interest, R = 10%

Annual installment, x = Rs. 3872

Total number of installments, N = 2

Formula used:

P = [x/(1 + R/100)] + [x/(1 + R/100)²] +.....+ [x/(1 + R/100)ⁿ]

where,

P = Principal borrowed, x = Annual Installments, R = Rate of Interest

Calculation:

Since, Total number of installments is 2.

Value of 2 installments = 2 × Rs. 3872 = Rs. 7744

Now,

P = [x/(1 + R/100)] + [x/(1 + R/100)2]

⇒ P = [3872/(1 + 10/100)] + [3872/(1 + 10/100)²]

⇒ P = [3872/(11/10)] + [3872/(11/10)²]

⇒ P = [(3872 × 10)/11] + [(3872 × 100)/121]

⇒ P = 3520 + 3200 = Rs. 6720

Total interest charged = Value of 2 installments - Principal borrowed

⇒ Total interest charged = Rs. 7744 - Rs. 6720 = Rs. 1024

∴ The total interest charged in this installment scheme is Rs. 1024.

Given:

A and B are moving towards each other from places X and Y

After meeting at point M they reach each other's starting points X and Y in 3.2 hours and 7.2 hours.

Formula:

S₁ : S₂ = √(T₂/T₁)

S₁ = Speed of car A, S₂ = Speed of car B

T₁ = Time taken by car A to cover distance

T₂ = Time taken by car B to  cover distance 

Concept:

In relative speed when both objects come to each other their speed becomes the sum of their speed. 

Calculation:

Let T be the time taken by them to reach point M.

S₁ : S₂ = √(7.2/3.2) = 3 : 2

Let the ratio constant be x

then S₁ = 3x and S₂ = 2x

So, T = {(2x × 7.2) + (3x × 3.2)}/(3x + 2x) hours

⇒ T = (14.4x + 9.6x)/5x hours

⇒ T = 24x/5x = 4.8 hours

∴ The time taken by them to reach point M was 4.8 hours.

Given:

The average of 14 numbers is 73.5

60 and 63 were replaced by 58 and 70

Calculation:

Sum of all terms = Average of terms × Number of terms 

Sum of 14 terms = 14 × 73.5 

Sum of 14 numbers after replacing the two-digit = 14 × 73.5 + (58 +70) – (60 +63)

Average = sum of all numbers/Total numbers

⇒ 75 = (14 × 73.5 + 128 – 123 + x)/15

⇒ 75 = (1034 + x)/15

⇒ 1125 = 1034 + x

⇒ 91 = x

∴ The value of x is 91

Shortcut Trick

Let x = t + 73.5

Increasing average =  ((58 +70) – (60 +63) + t)/Number of terms 

⇒ 1.5 = (5 + t)/15

⇒ 22.5 = 5 + t

⇒ 17.5 = t

x = 17.5 + 73.5 = 91

∴ The value of x is 91

Given:

The income of A = 60% more than the income of B.

The income of C = 45% less than the income of (A + B).

Formula used:

Percentage = {(Final value - Initial value)/Initial value} × 100

Calculation:

Let the income of B be 100.

So, income of A = 100 + (100 × 60/100) = 160

Income of A + B = 100 + 160 = 260

And, income of C = 260 - (260 × 45/100)

⇒ Income of C = 260 - 117 = 143

Required percentage difference = {(160 - 143)/160} × 100

⇒ 170/16 = 10.625%

∴ C's income is 10.625% less than that of income of A.

Shortcut Trick Let income of B = 100%

A ∶ B ∶ C = 160 ∶ 100 ∶ 143

Required percentage = [(160 - 143)/160] × 100 = 170/16 = 10.625%

∴ C's income is 10.625% less than that of incoe of A

Given:

Percentage of passing students in school A = 65%

Percentage of passing students in schools A and B = 75%

Compared to school B 100% more students appeared in school A.

Calculation:

Let the number of students in school A is Y and the number of passing student in school B is P%

Percentage of passing students in school A = Y × 65%

Percentage of passing student in school A = Y × (65/100)

Total number of students in school B = 2Y

Percentage of passing students in school B = 2Y × P%

Percentage of the total number of passing students in schools A and B = (Y + 2Y) × 75%

⇒ Y × 65% + 2Y × P% = (Y+ 2Y) × 75%

⇒ Y × (65/100) + 2Y × (P/100) = (3Y) × (75/100)

⇒ 2Y × (P/100) = (225Y/100) – (65Y/100)

⇒ 2Y × (P/100) = (160Y/100)

⇒ 2Y × (P/100) = (160Y/100)

⇒ (P/100) = (80/100)

⇒ P = 80

Percentage of failed student in school B = 100% – 80%

Percentage of failed students in school B = 20%

∴ The percentage of failed students in school B is 20%

Alternate Method 

Let the Total number of student in school A is 100 and the failed student in school B is Q%

Percentage of Failed students in school A = 100 × 35%

Percentage of Failed student in school A = 100 × (35/100)

Percentage of Failed student in school A = 35

100% more students than those in school A, appeared in the same examination from school B.

⇒ Total number of student in school B = 100 × (200/100)

⇒ Total number of students in school B = 200

⇒ Total number of students in schools A and B = (100 + 200)

⇒ Total number of students in schools A and B = 300

Total number of students who failed in schools A and B = 300 × 25%

⇒ 100 × 35% + 200 × Q% = 300 × 25%

⇒ 100 × (35/100) + 200 × (Q/100) = 300 × (25/100)

⇒ 35 + 2 × Q = 75

⇒ 2Q = 40

⇒ Q = 20

∴ The percentage of students who failed in school B is 20%

Shortcut Trick Let total students in school A be 100

Apassed = 65% of 100 = 65

Btotal = 200% of 100 = 200

(A + B)passed = 75% of (A + B)total = 75% of 300 = 225

Bpassed = 225 - 65 = 160

Bfailed = [(200 -160)/200] × 100 = 20%

Given:

The rate of interest on a sum for the first 3 years is 8% p.a.

For the next 4 years, it is 10% p.a.

For the period beyond 7 years, it is 16% p.a.

A person gets Rs. 11340 simple interest after 10 years.

Concept used:

For simple interest, the rate of interest will always be the same every year.

The principal will always be considered as 100%

Formula used:

S.I = PRT/100

Where S.I is Simple interest, P is Principal, T is time period

Calculation:

The overall rate of interest for the first 3 years at 8% = (3 × 8)% = 24%

The overall rate of interest for the next 4 years at 10% = (4 × 10)% = 40%

Now, according to the question the person invested his principal for 10 years.

So, for the remaining 3 years, the rate of interest will be 16% per annum.

Then, his rate of interest for 3 years will be (16 × 3)% = 48%

Total interest will be received for 10 years is (24% + 40% + 48%) = 112% of the principal.

So, 112% = 11340

⇒ 100% = 11340/112 × 100

⇒ 10125

∴ He invested Rs. 10125 for 10 years.

Shortcut Trick SI = PRT/100

11340 = P × [(8% × 3) + (10% × 4) + (16% × 3)]

⇒ 11340 × 100 = P × 112

⇒ P = Rs. 10125

Given:

The curved surface area of right circular cylinder is 1320 cm²

Radius of the base is 10.5 cm

Formula used:

Curved surface area of cylinder = 2πrh

Volume of the cylinder = πr²h

Where r = radius, h = height

Calculations:

Curved surface area of cylinder is 2πrh

⇒ 2πrh = 1320

⇒ 2 × (22/7) × 10.5 × h = 1320

⇒ h = (1320 × 7)/(2 × 22 × 10.5) = 20 cm

Height of the cylinder = 20 cm

Volume of the cylinder = πr²h

⇒ (22/7) × 10.5 × 10.5 × 20

⇒ 48510/7 = 6930 cm3

∴ The volume of the cylinder is 6930 cm³

 

Curved surface area of cylinder = 2πrh

Given:

Amount divided among A, B, C, and D = Rs.16,380

A : B = 1 : 3, B : C = 2 : 5, and C : D = 2 : 3

Calculation:

Step 1  

Step 2

Step 3

A : B : C : D = (1 × 2 × 2) : (3 × 2 × 2) : (3 × 5 × 2) : (3 × 5 × 3)

⇒ A : B : C : D = 4 : 12 : 30 : 45

Now, (4 + 12 + 30 + 45)R = 16,380

⇒ 91R = 16380

⇒ R = 180 

⇒ 30R = 180 × 30 = Rs. 5400

∴ The share of C is Rs. 5400.

Shortcut Trick

∴ A ∶ B ∶ C ∶ D = 4 ∶ 12 ∶ 30 ∶ 45

C's share = [16380/91] × 30 = Rs. 5400

Given:

 x is the least number of 4 digits.

The remainder is 7 in each case when x is divided by 12, 15, 20 27.

Concept: 

The least number that is divisible by all given numbers will be the LCM of given numbers.

Calculation:

L.C.M of 12, 15, 20 27 = 540

In each case, the remainder is 7

x = 540k + 7, Where k is a natural number

Put k = 1,2,3,4,..............

When k = 1,

x = 540 × 1 + 7

⇒ x = 547

When k = 2,

x = 540 × 2 + 7

⇒ x = 1080 + 7

⇒ x = 1087

Which is the least 4-digit number which leaves 7 as the remainder in each case when divided by 12, 15, 20, and 27..

Sum of digits of x = 1 + 0 + 8 + 7

⇒ Sum of digits of x = 16

∴ The sum of digits of the number is 16.

Given:

$\left( {0.5\overline 8 ÷ 0.\overline {53} } \right) × \frac{5}{{33}} + \frac{{10}}{{21}} ÷ 1\frac{1}{{14}}$ of $\frac{5}{3} - \frac{5}{3} × \frac{1}{{10}}$ 

Concept used:

Solution:

 $\left( {0.5\overline 8 ÷ 0.\overline {53} } \right) × \frac{5}{{33}} + \frac{{10}}{{21}} ÷ 1\frac{1}{{14}}$ of $\frac{5}{3} - \frac{5}{3} × \frac{1}{{10}}$

⇒ {(58 - 5)/90 ÷ (53/99)} × (5/33) + (10/21) ÷ (15/14) × (5/3) - (1/6)

⇒ {(53/90) ÷ (53/99)} × (5/33) + (10/21) × (14/15) × (5/3) - (1/6)

⇒ (11/10) × (5/33) + (2/3) × (2/5) - (1/6)

⇒ 1/6 + 4/15 - 1/6

⇒ 4/15

∴ $\frac{{4}}{{15}}$ is the value of $\left( {0.5\overline 8 ÷ 0.\overline {53} } \right) × \frac{5}{{33}} + \frac{{10}}{{21}} ÷ 1\frac{1}{{14}}$ of $\frac{5}{3} - \frac{5}{3} \times \frac{1}{{10}}$.

Given:

Marked Price of the article, MP = Rs. 240

Discount% = 10, Profit% = 8

Formula Used:

Discount% = {(MP – SP)/MP} × 100

Profit% = {(SP – CP)/CP} × 100 

where, MP = Marked Price, SP = Selling Price and CP = Cost Price

Calculation:

Here, Discount% = {(MP – SP)/MP} × 100

⇒ 10 = {(240 – SP)/240} × 100

⇒ 10/100 × 240 = 240 – SP

⇒ 24 = 240 – SP

⇒ SP = 240 – 24 = 216

Now, Profit% = {(SP – CP)/CP} × 100

⇒ 8 = {(216 – CP)/CP} × 100

⇒ (8/100) × CP = 216 – CP

⇒ CP + (8/100) × CP = 216

⇒ (108/100) × CP = 216

⇒ CP = 216 × 100/108 = 200

∴ The cost price of the article is Rs. 200

Shortcut Trick

Here, MP = 240, and discount is 10%

So, SP = 90% of 240

⇒ SP = 90/100 × 240 = 216

Now, Profit is 8%

So, SP/CP = 108/100

⇒ CP = 216 × 100/108 = 200

∴ The cost price of the article is Rs. 200

Given:

Time taken by A to complete the work is 10 days.

Time taken by B to complete the work is 15 days.

Time taken by C to complete remaining work is 12 days.

Concept Used:

Time taken = (Total work done)/(Efficiency)

Calculation:

Let the work done by A, B and C be in Units.

Total Work done by (A + B) = L.C.M of (10, 15) 

⇒ 30 Units

Now,

Efficiency of A = Total Work/Time taken

⇒ 30/10 =  3 units per day

Efficiency of B = Total Work/Time taken

⇒ 30/15 =  2 units per day

Total Work done by (A + B) in 4 days = (Sum of efficiency of A and B) × 4

⇒ (3 + 2) × 4 = 20 units

Remaining Work = (30 - 20) = 10 units

Efficiency of C for completing remaining work = 10/12

⇒ (5/6) unit per day

Then,

Time taken by C to complete (4/9) part of original work = 30 × (4/9) × (6/5)

⇒ 16 days

∴ Time taken by C to complete (4/9) part of original work is 16 days.

Shortcut Trick 

(A + B) = 4 × 5 = 20

Efficiency of C = (30 - 20)/12 = 10/12 = 5/6

Time taken by C to complete (4/9) part of original work = [30 × (4/9)]/(5/6)

⇒ 30 × (4/9) × (6/5) = 16 days

Given:

C.P. of 36 kg sugar = 1620

Profit = S.P. of 6 kg sugar

C.P. = Cost price,  S.P. = Selling price

Calculation:

Here Quantity of sold sugar = Quantity of sugar bought - profitable sugar

⇒ Quantity of sold sugar = (36 - 6) kg

⇒ Quantity of sold sugar = 30 kg

So after selling 30 kg of sugar we get C.P. of 36 kg

So, 36 × C.P. = 30 × S.P.

⇒ Rs.  1620 = 30 × S.P.

⇒ S.P. = Rs. 1620/30 = Rs. 54

∴ Roshan's selling price per kg is Rs. 54.

Given:

Divisor is 18 times of quotient and 9 times the remainder

Remainder is 26

Formula used:

Dividend = Divisor(D) × Quotient(Q) + Remainder

Calculation:

If D = 18Q, R = 26

Dividend = Divisor(D) × Quotient(Q) + Remainder

⇒ 18Q × Q + 26      ----(1)

If D = 9 × 26, R = 26 

Dividend = Divisor(D) × Quotient(Q) + Remainder

⇒ 9 × 26 × Q + 26      ----(2)

Compare equation (1) and (2)

⇒ 18Q × Q + 26 = 9 × 26 × Q + 26 

⇒ 18Q² = 9 × 26 × Q

⇒ Q = 13

Put the value of Q in equation (2)

Dividend = 9 × 26 × 13 + 26

⇒ 26(117 + 1)

⇒ 3068

∴ The dividend is 3068

Given:

The perimeter of a rhombus = 148 cm

One diagonal = 70 cm

The ratio of sides of rectangle = 7 : 3

Concept used:

The diagonals of a rhombus are intersected each other at right angle.

Formula Used: 

Area of Rhombus = 1/2 × d₁ ×  d₂

where,

d_1, d₂ are diagonals of the rhombus.

Calculation:

In right-angle triangle  ΔAOB,

⇒ AB² = AO² + OB²

⇒ (37)² = (35)² + OB²

⇒ OB² =1369 - 1225 = 144

⇒ OB = 12

AC = 2 × OB =2 × 12 = 24 cm

Area of rhombus = 1/2 × 24 × 70 = 840

Now, Area of rhombus = Area of rectangle

Let the side of rectangle be 7x and 3x respectively.

⇒ 7x × 3x = 840

⇒ x² = 40

⇒ x = 2√10

Longer side of rectangle = 7x = 7 × 2√10 = 14√10

∴ Longer side of rectangle is 14√10 cm.
