Given:

Calculation:

∴ We need 150,000 - 50,000 = 100,000 more doses.

Given:

Two trains of length 220 m and 190 m are running on parallel tracks in opposite directions at the speed of 80 km/hr and 64 km/hr respectively.

Formula Used:

Let, 'a' meter long train is running at the rate of x m/sec and 'b' meter long train is running at the rate of y m/sec in its opposite direction on parallel tracks, then 

Time taken by trains in crossing each other = \(\left (\frac{a+b}{x+y} \right ) ;\)

Calculation:

x = 80km/hr = 80 × 5/18 m/sec = 200/9 m/sec

y = 64km/hr = 64 × 5/18 m/sec = 160/9 m/sec

Time taken by trains in crossing each other = (a + b)/(x + y)

⇒ (200 + 190)/(200/9 + 160/9) = 410/(360/9) = 410/40 

⇒ 10.25 sec

∴ They cross each other in 10.25 sec

Given:

2a × 3b × 7c = 1176

Calculation:

Factors of 1176 = 2 x 2 x 2 x 3 x 7 x 7 = 2³ x 3¹ x 7²

Now, According to question,

⇒ 2a × 3b × 7c = 23 x 31 x 72

On comparing the base of both sides -

a = 3

b = 1

and c = 2

So, 2a + 3b + 7c = 2³ + 3 + 7²

⇒8 + 3 + 49

⇒ 60

Hence, 2a + 3b + 7c  = 60 is correct answer.

Given:

p% of 12 = q% of 20,

Concept Used:

\(If; \frac{p}{q}=\frac{m}{n}\Rightarrow \frac{p+q}{p-q}=\frac{m+n}{m-n}\)

Calculation:

p% of 12 = q% of 20 

p × 12 = q of 20

p/q = 120/12 = 5/3

∴ (p - q): q = 2 : 3 is correct answer.

Given:

Numbers = 2048, 2052, 3526

Calculation:

Hence, 2 is the largest common factor available in all numbers

∴  2 is largest number which divides all the  2048, 2052, 3526 completely.

Given:

By selling an article for Rs. 800 more, Kavita gains 7% instead of 13% loss on her sale.

Concept Used:

If a% loss becomes b% gain on selling Rs. M more than initial than

\((a+b)% of ;CP = M;\)

Calculation:

⇒ 20% of CP = 800

CP = 800 × 100/20 = 800 × 5 = Rs.4000

∴ Cost Price of article is Rs 4000.

Given:

⇒ 8.6% of p = 43

Calculation:

⇒ 8.6 % of p = 43

p = 43/8.6% = 430/86 × 100 = 5 × 100 = 500 

∴ The value of p is 500.

Given:

Time taken by pipe A to fill the tank = 16 hours

Time taken by pipe B to fill the tank = 18 hours

Concept Used:

Volume/Capacity of tank = LCM(time taken by pipe A), (Time taken by pipe B)

Calculation:

Volume/Capacity of tank = LCM(time taken by pipe A), (Time taken by pipe B) = LCM [16, 18] = 144

A and B fill water together 4 hours so,

In 4 hours water filled by A + B = (9 + 8) × 4 = 17 × 4 = 68 unit

Remaining volume of tank = 144 - 68 = 76 units

These 76 units were filled by pipe B,

Time taken by pipe B to fill remaining tank = 76/8 = 9.5 hours

Pipe B take 9.5 hours more to fill the remaining tank.

Given:

P = 18000 Rs

R = 13%

n = 2 years

Formula Used:

.\(CI=P\left [ \left ( 1+\frac{R}{100} \right )^n - 1 \right ]\)

Calculation:

\(CI=P\left [ \left ( 1+\frac{R}{100} \right )^n - 1 \right ]\)

⇒ 18000 [(1 + 13/100)² - 1]

⇒ 18000 [{(100 + 13)/100}2 - 1]

⇒ 18000 [(113/100)2 - 1]

⇒ 18000 [(113/100) × (113/100) - 1]

⇒ 18000 [12769/10000 - 1]

⇒ 18000 [(12769 - 10000)/10000]

⇒ 18000 [(2769/10000] = 18 × 2769/10 = 49842/10 = 4984.2

∴ Compound interest is Rs. 4984.2

Given:

l + b + h = 19 units

d = 15 units

Formula Used:

Diagonal of cuboid = √(l²+ b² + h²)

Total surface area of cuboid = 2(lb + bh + hl)

⇒ (l + b + h)² = l² + b2 + h2 + 2(lb + bh + hl)

Calculation:

Diagonal of cuboid = √(l2+ b2 + h2) = 15 units

(l2+ b2 + h2) = 15 × 15 = 225

We know that,

⇒ (l + b + h)2 = l2 + b2 + h2 + 2(lb + bh + hl)

⇒ (19)² = 225 + 2(lb + bh + hl)

⇒  2(lb + bh + hl) = 361 = 225 = 136

∴ Total surface area of cuboid = 136 unit²

Given:

\( {3x + 2y\ \ \over 3x - 2y}=\frac{17}{13}\)

Formula Used:

Componendo - Dividendo Rule→

\(If \frac{a}{b}=\frac{c}{d};then,;\frac{a+b}{a-b}=\frac{c+d}{c-d}\)

Calculation:

\( {3x + 2y\ \ \over 3x - 2y}=\frac{17}{13}\)

⇒ (3x + 2y)/(3x - 2y) = (15 + 2)/(15 - 2)

⇒ 3x/2y = 15/2

⇒ 3x/y = 15/1

⇒  3/7 × 3x/y = 3/7 × 15/1 

⇒ 9x/7y = 45/7

∴  9x : 7y = 45 : 7 is correct answer.

Given:

A train overtakes two persons running in the same direction at 4 kmph and 6 kmph and passes them completely in 12 seconds and 15 seconds respectively.

Concept Used:

If a train overtakes two persons who are walking in the same direction in which the train is going, at the speed of s₁ m/sec & s₂ m/sec and takes t1 & t₂ sec then,

\(Length;of;train=(s_1- s_2)\left ( \frac{t_1 t_2}{t_1- t_2} \right );;\)

Calculation:

s₁ = 4 kmph = 4 × 5/18 = 10/9 m/sec

s₂ = 6 kmph = 6 × 5/18 = 15/9 m/sec

Length of train = (s₁ - s₂) (t₁t₂/t₂ - t₁) = (10/9 - 15/9) × (12 × 15/(12 - 15))

⇒ -5/9 × 180/-3 = 100/3 metres

∴ Length of train is 100/3 metres

Given:

Numbers are = 352, 246, 252, 155

Concept Used:

Divisibility rule of 7 -

To check whether given number is divisible by 7 or not, subtract the double of unit digit from the remaining part of number, now if the result is multiple of seven or 0 then it is divisible by 7.

Given:

a + b = 99

HCF = 3

LCM = 660

Formula Used:

Product of two numbers = HCF × LCM

(a - b)² = ( a + b)² - 4ab

Calculation:

Products of two numbers = HCF × LCM

ab = 3 × 660 = 1980

a + b = 99

(a - b)² = ( a + b)2 - 4ab

⇒ (99)² - 4 × 1980 = 9801 - 7920 = 1881

∴ ( a - b)² = 1881 is correct answer.

Given:

Discount = 30%

Formula Used:

\(SP=\frac{(100-R%)MP}{100}\)

\(Mark-up%=\frac{MP-CP}{CP}\times100%\)

Calculation:

SP = (100 - R%) MP/100

SP = ( 100 - 30) MP/100

SP = 7MP/10

MP/SP = 10/7

According to question,

SP = CP

MP/CP = 10/7

Mark up % = (MP - CP)/CP × 100%

⇒ (10 - 7)/7 × 100% = 300/7% = 42.8572 ≈ 42.86%

Given:

∴ The surface area of the cube = 1350 cm²

Given:

⇒  2p = 4 × 2q  

⇒ 9 × 3p = 3-q 

Formula Used:

a^m × aⁿ = a^{m + n}

If, a^m = aⁿ then m = n

Calculation:

We have given,

⇒ 2^p = 4 × 2^q

⇒ 2p = 2² × 2q

⇒ 2p = 2^{2 +} q

p = 2 + q

p - q = 2

∴ p - q = 2 is correct answer.

Given:

Formula Used:

Profit = SP - CP

Calculation:

Profit = SP - CP

• The next sentence i.e. “Most ultralights are sold as kits and take about 40 hours to assemble.” is continuing the specification in addition to the previous sentence.
• The next sentence adds the flying experience to the specifications, "Flying an ultralight airplane is so easy that a pilot with no experience can fly one."
• The next sentence is telling us about the accident probability of the plane, "Accidents are rarely fatal or even serious because the ultralight lands so slowly and gently and carries very little fuel." Which can be associated with the sentence given at the last of the paragraph describing about the safety features of the airplane.

Therefore, the correct sequence of the jumble para would be RQSP.
