Question : 1 [SSC DEO 2009]
The salary of a person is decreased by 25% and then the decreased salary is increased by 25%. His new salary in comparison with his original salary is
a) 6.25% less
b) 6.25% more
c) the same
d) 0.625% less
Answer »Answer: (a)
Effective change
= $(–25 + 25 - {25 × 25}/100)%$ = – 6.25%
The negative sign shows decrease.
Using Rule 3,
If an amount is increased by a% and then it is reduced by a% again, then percentage change will be a decrease of $a^2/100%$
Percentage decrease = $a^2/100 % = (25)^2/100$
= $625/100$ = 6.25%
Question : 2
What per cent decrease in salaries would exactly cancel out the 20 per cent increase?
a) 33$1/3$%
b) 16$2/3$%
c) 20%
d) 18%
Answer »Answer: (b)
Using Rule 8,
If the income of a man is A% more than another man, then income of another man is less in comparison to the 1st man by
$(A/(100 + A)× 100)%$
Simple method
Required answer = $(20/{100 + 20} × 100)$%
= $(20/120 × 100)% = 50/3% = 16{2}/3%$
Question : 3 [SSC CGL Prelim 2003]
Radha spends 40% of her salary on food, 20% on house rent, 10% on entertainment and 10% on conveyance. If her savings at the end of a month are Rs.1500, then her salary per month (in Rs.) is
a) Rs.6000
b) Rs.7500
c) Rs.8000
d) Rs.10000
Answer »Answer: (b)
Radha's total percentage expenditure
= (40 + 20 + 10 + 10)% = 80%
Percentage savings =100 – 80 = 20%
Now, 20% of her total salary = 1500
Her total salary = ${1500 ×100}/20$ = Rs.7500
Using Rule 20,
Here, Monthly income = $100/{100 - (40 + 20 +10 +10)} ×1500$
= $150000/{100 – 80} = 150000/20$ =Rs.7500
Question : 4 [SSC HSL DEO & LDC 2010]

a) 83$2/3$%
b) 16$2/3$%
c) 83$1/3$%
d) 16$1/3$%
Answer »Answer: (b)
Using Rule 8,
Required percentage = $20/{100 + 20} × 100$
= $50/3 =16{2}/3%$
Question : 5 [SSC SO 2003]
If the total monthly income of 16 persons is Rs.80,800 and the income of one of them is 120% of the average income, then his income is
a) Rs.6,160
b) Rs.6,060
c) Rs.5,050
d) Rs.6,600
Answer »Answer: (b)
Let the required income be Rs.x Average monthly income
= Rs.$(80800/16)$ = Rs.5050
x = 120% of 5050
= Rs.$(120/100 × 5050)$ = Rs.6060
