Let there be 100 items worth 100 rupees total. So, the seller sells 75 at 75 * 124/100 = 93 rupees.

and 25 at 25 rupees.

Total profit = 93 + 25 – 100 = 18 rupees

Profit % = 18/100 = 18%

There are 40 women and 60 men in the group. 40 % of the women and 60% of the men = 40 * 40% + 60 * 60 % = 52

Let’s say Nikita’s salary is x, hence Rajendra’s salary will be $\frac{6x}{5}$, hence Nikita’s salary is $\frac{x}{5}$ lesser than that of Rajendra’s salary.
So percentage = $\frac{\frac{x}{5}}{\frac{6x}{5}} \times 100 = 16.66 \%$

Let the price be 180 Rs. 18 items were purchased at 180 rupees and 15 items were sold at 180 rupees.

So, cost price is 10 rupees and selling price is 12 rupees.

So, profit percent = 20%

Let the number of students in the class be 100.
Number of girls = 30
Number of boys = 70
Number of girls selected to the team = 20% of 30 = 6
Number of boys selected to the team = 30% of 70 = 21
So, percentage of girls in the team = 6/27 * 100% = 22.22%

Initial price of the watch = 1000
After 10% decrease, price of the watch = (90/100)*1000 = 900
After 10% increase, price of the watch = (110/100)*900 = 990
So, the new price of the watch = Rs 990
Difference between the new price and old price = 1000 – 990 = Rs 10

Let the number of questions in the paper be N.
Number of technical questions = 40% of N = 2N/5
Number of non-technical questions = 60% of N = 3N/5
Number of questions left unanswered by the student = 50% of technical questions and 40% of non-technical questions = N/5 + 6N/25 = 11N/25
So, 11N/25 = 66
=> N = 66*25/11 = 150

Suppose, there are 100 fruits in the basket.
=> 30 are apples and 70 are oranges
60% of apples are ripe => 30 * 0.6 = 18 apples are ripe => 12 apples are not ripe.
70% of oranges are ripe => 70 * 0.7 = 49 oranges are ripe => 21 oranges are not ripe.
=> Total number of fruits that are not ripe = 12 + 21 = 33
=> 33% of fruits are not ripe

Let the price of bananas be x Rs/ banana.

If the price falls by 20%, cost of banana = .8x

Number of bananas for Rs. 10 = 10/.8x

But 10/.8x- 10/x = 5

So, x = .5

65% of the stamps = 520

100% = ?

520/.65 = 800

Let the CP of 18 articles = SP of 15 articles = 180 Rs.

CP of one article = 10 Rs

SP of one article = 12 Rs

Profit % = 20%

Let the number be x. Hence, 4/5*4/7*x=16. Hence, x=5*7=35.

Let x be the total amount with Mr.Agarwal

money given to his wife=30% of x

money given to his daughter=35% of x

money given to each son=(35/5)% of x=7% of x

given, 7% of x=14,000

=>x=Rs.2,00,000

Let the initial quantity of the mixture be x litres.

Syrup = .6x

Water = .4x

If 5 litres of syrup is added, syrup = .6x + 5

water = .4x

But .4x/x+5 = 35%

So, x = 35 litres

percent of window remaining to be painted=100%-(percent already painted)=(100-61)%=39%

loss%=$\frac{CP-SP}{CP}$×100=$\frac{.1}{1000}\times100$%=.01%

Percentage of loss = (CP-SP)/CP = 200/1200 = 16.67%

Let Sunil’s salary be 100 Rs.

Anil’s salary = 133.33 Rs

Sunil’s salary is less than Anil’s by 33.33/133.33 = 25%

Let the amount that is fixed be 210 Rupees

He used to get 15 litres of petrol for Rs. 210 earlier and then only 14 litres.

Initial cost of petrol = 210/15 = 14 Rs

Final cost of petrol = 210/14 = 15 Rs.

% rise in petrol price = 100/14 = $7 \frac {1}{7}$
