Answers & Solutions:
1) Answer (B)
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%
2) Answer (D)
There are 40 women and 60 men in the group. 40 % of the women and 60% of the men = 40 * 40% + 60 * 60 % = 52
3) Answer (B)
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%
4) Answer (D)
percent of window remaining to be painted=100%-(percent already painted)=(100-61)%=39%
5) Answer (A)
Percentage of loss = (CP-SP)/CP = 200/1200 = 16.67%
6) Answer (C)
Let his original salary be 100 Rs.
Decreased salary = 100 – 10% = 90 Rs.
Amount to be increased = 10 RS
Percentage = 10*100/90 = $11\frac{1}{9}$
7) Answer (C)
Let the cost of each orange be y.
Cost of 10 apples =10y
Selling price of 10 apples =Cost of 12 apples =12y
The profit for selling 10 apples=12y-10y=2y
Thus profit%=(2yx100)/10y= 20%
8) Answer (C)
Let say,cost price of one article is c and selling price of one article is s.
So, cost price of 120 article is 120c.
And selling price of 80 articles is 80s.
So, 120c=80s.
or,$(s/c)=120/80=1.5.$
or,$(s-c)/c=1.5-1=0.5$.
So,Profit percentage is 50%.
C is correct choice.
9) Answer (C)
C.P = 11000, S.P = 13500
Gain = 13500 – 11000 = 2500
Gain% = $\frac{2500\times\ 100}{11000}=22.7$%.
10) Answer (A)
1 min 12 sec = 72 sec
1 hour = 3600 sec
Required percentage = $\frac{72}{3600}\times\ 100$ = 2%
11) Answer (C)
25%=$\ \frac{\ 1}{4}$, if divya marks= 4 then sham marks =5
divya marks less than by sham in %=$\ \frac{\ 5-4}{5}\times\ 100$ =20%
Hence option ‘C’is correct.
12) Answer (B)
A boy has 120 balls of which some are white and the remaining are black.
Percentage of white balls is 45%.
Total white balls $=0.45\times 120 = 54$
Total black balls $= 120-54 = 66$
Option B is correct.
13) Answer (B)
Let the cost price be x. Then,
selling price = $1\frac{1}{3}x$
= $\frac{4}{3}x$
Gain = Selling Price – Cost Price
= ₹($\frac{4}{3}x$ – x)
= ₹$\frac{4x -3x}{3}$
= ₹$\frac{x}{3}$
Gain % =$\frac{gain}{cp}\times 100$
=$\frac{\frac{x}{3}{x}\times 100$
= ₹$\frac{100}{3}%$
= $33\frac{1}{3}$%
14) Answer (A)
Since, Expenditure = price$\times$ consumption
And Expenditure is constant. So, price is inversely proportional to consumption.
Ratio of price = 10 : 13
So, ratio of consumption = 13 : 10
% decrease in consumption = $\frac{3}{13}$ $\times100$
= $\frac{300}{13}$%
15) Answer (B)
Number of hours in a day = 24 hours
Number of minutes per hour = 60 minutes
Then, Number of minutes per day = 24*60 = 1440 minutes
Therefore, Required percentage = $\dfrac{18}{1440} \times 100 = 1.25$%
