To solve this question, we can apply the net% effect formula

x+y\frac{xy}{100}

Let's take x = 35% and y = – 17.5%

By the net% effect formula, we get

Profit % = (35-17.5- \frac{35 \times 17.5}{100})% = (17.5 – 6.125)% = 11.375%

Let the first discount be x%.

Then, 85% of (100 – x)% of 200 = 136

\frac{85}{100} \times \frac{100-x}{100} \times 200=136

or, 8500 – 85x = 136 × 50 = 6800

or, 85x = 1700

Therefore, x = 20%

Let the speed of Bus = B kmph
Let the speed of Car = C kmph
Distance = 550 km
\frac{250}{C} + \frac{300}{B} = 12.5 .........(1)
\deac{350}{C} + \frac{200}{B} = 12 ...........(2)
Solving eq (1) and eq (2)We get;
Speed of Bus = 40 kmph
Speed of Car = 50 kmph

According to question,

Difference=1t

1t = 1/4 hours.

Initial Timing = 75 minutes.

Distance = 60 km

Initial Speed = 60\times \frac{4}{5}

Speed = 48 kmph

6s = 48 kmph

1s = 8 kmph

Decrease in speed= 8 kmph

Piper Perabo’s monthly income = Rs 32000

Rebecca Hall’s monthly income = 32000\times (1+\frac{1}{15})

= 32000\times (\frac{115}{100})
=Rs. 36800

Beyoncé’s monthly income= 3 \times 36800

=110400

Beyoncé’s annual income= 12 \times 110400

= Rs. 1324800

Let the salary in 2009 be x

Salary in 2010=1.1x

Salary in 2011= 1.1x \times 1.1

=1.21x

1.21x = 22385 

x = 18500

Sum of the present ages of husband, wife and child = (27 \times 3 + 3 \times 3) years = 90 years.

Sum of the present ages of wife and child = (20 \times 2 + 5 \times 2) years = 50 years.

Therefore, Husband's present age = (90 - 50) years = 40 years

By the rule of alligation:
8%                               18%

Mean Profit
18%

4                                        6

So, ratio of 1st and 2nd parts = 4 : 6 = 2 : 3.
Therefore, Quantity of 2nd kind = (\frac{3}{5} \times 1000)kg = 600 kg.

Suppose the can initially contains 7x and 5x litres of mixtures A and B respectively

Quantity of A in mixture left = (7x-\frac{7}{12} \times 9 =7x-\frac{21}{4}

Quantity of B in mixture left = (5x-\frac{7}{12} \times 9 = 5x-\frac{15}{4}

=> \frac{7x-\frac{21}{4}}{5x-\frac{15}{4}+9}=\frac{7}{9}

=> \frac{28x-21}{20x+21}=\frac{7}{9}

=> x=3
3 \times 7 =21 ltrs. of liquid A was contained initially.

Ben Foster would have done 47/60 work in 47 days. 

The remaining work i.e. 13/60 must have been done by Barry Pepper and Ben Foster together. They can do the whole work in \frac{60 \times 70}{(60 + 70)} = \frac{60\times 70}{130} = \frac{420}{13} days.

So, they would have done 13/60 work in \frac{420}{13} \times \frac{13}{60} = 7 days. Therefore, Barry Pepper left work after 7 days.

The first letter is moved forward by 6 steps.

The second letter is moved forward by two vowels.

Third letter is moved backward by 3 steps.

For the fourth letter, the number of its position is multiplied by 2 and the corresponding  letter is obtained.

The fifth letter is moved backward by 7 steps.

The sixth letter is moved forward by two steps.

Hence, the correct answer is LIRNAV.

The third sentence concludes that prohibiting commercial vehicles with more than 8 wheels from city-roads would force most vehicles away from city-roads.

The conclusion cannot be true unless it is true that, as 2 says, most trucks that use city-roads have more than 8 wheels. Therefore, the first sentence's conclusion assumes this choice, which is thus the best answer.

The first letter is moved forward by 5 steps.

The second number is moved forward by a prime number.

The third letter is moved backward by 4 letters.

Fourth letter is moved backward by one vowel.

Hence, the correct answer is H3SO.
