Answers & Solutions:
1) Answer (B)
Let’s say B’s income is 100
Hence A’s income will be 50
Now B’s income is 50 more than A’s
Hence it is $\frac{50}{50}\times100$ percent ($\frac{d}{Ai}\times100$ where d is difference in income and Ai is A’s income) more than A’s
2) Answer (C)
Let’s say 1.14 is $x$ percent of 1.9
hence 1.14 = $\frac{1.9\times x}{100}$
$x$ will be 60
3) Answer (C)
Given 60% of A = 48% of B
Hence A:B = 48 : 60
or A:B = 4 : 5
4) Answer (C)
Let’s say price of article is 100
After first increase its price will be 100(1+ $\frac{10}{100}$) = 110
Now second increment will be applied on 110
Hence new price will be 110(1+ $\frac{10}{100}$ ) = 121
Which is 21 more than before any increment
Hence total percentage increment = 21
5) Answer (C)
let’s say B’s income is 100
A’s income will be 75
B’s income is 25 greater than A’s
hence B’s income is $\frac{25}{75} \times 100$ percent more than A’s
6) Answer (A)
let’s say marked price 100
so for first discount of 30% selling price will be 70
and for two successive discounts of 20% and 10% selling price will be 72 and difference will be 2
now when difference between both selling prices is 2, marked price is 100
so when difference between both selling prices is 72, marked price will be $\frac{100}{2} \times 72$ = 3600
7) Answer (C)
let’s say amount of electricity bill is 100
so reduction will be 4
hence when reduction is 4 amount of electricity bill is 100
now when reduction is 13 amount of electricity bill will be $\frac{100}{4}\times 13$
8) Answer (B)
We can assume that discount is on a price of 100
so after first discount of 10% its value will be = 90
now after second consecutive discount of 20% its value will be $90(1-\frac{20}{100})$=72
and after third consecutive discount of 30% its value will be $72(1-\frac{30}{100})$=50.4
hence it is a equivalent to a single discount of 100-50.4=49.6
9) Answer (D)
Let’s say its original price is 100
hence after first increment of 10% its value will be 110.
and after second consecutive increment of 20% its value will be 132
so when its value becomes 132 , original price is 100
now when its value becomes 33 , original price will be $\frac{100}{132} \times 33$
10) Answer (B)
Let’s say side of square is 100 unit
its area will be $10^{4} unit^{2}$
after 10% increment its value will be 110 unit
and area will become $1.21 \times 10^{4} unit^{2}$
change in area $ .21 \times 10^{4} unit^{2}$
percentage change will be 21
11) Answer (B)
let’s say length is 100 and width is also 100 hence area will be $10^{4}$ $unit^{2}$
after 10% increase, length will be 110 and 10% decrease in width, it will be 90 and area will be 9900 $unit^{2}$
%change in area will be = $\frac{100}{10000}\times100$ = 1%
12) Answer (B)
C does $\frac{1}{20}$ amount of work in a day.
And A+B do twice of work as much done by C or A+B=2C or $\frac{2}{20}$.
So A+B+C together will do $\frac{2}{20}+\frac{1}{20}=\frac{3}{20}$ amount of work in a day.
And complete work will be done in $\frac{20}{3}$ days.
13) Answer (A)
Having a gain of 12.5%, selling price will be $800 \times \frac{112.5}{100} = 900$
So after having a discount of 10% on marked selling price is 900
Hence marked price will be = $900 \times \frac{100}{90} = 1000$
14) Answer (A)
After having 20% discount price will be = $1500 \times \frac{80}{100}$ = 1200
So for net price of 1104 discount should be 1200-1104 = 96
%discount = $\frac{96}{1200} \times 100$ = 8%
15) Answer (A)
Let’s initial price is $x$, and sale is $y$ so revenue will be $xy$
After having discount of 20%, initial price will be $\frac{80x}{100}$ and sale will be $\frac{180y}{100}$ , hence new revenue is $1.44xy$.
Increment in revenue will be $0.44xy$ i.e. equal to 44%
