Ravi's salary was reduced by 25%.Percentage increase to be effected to bring the salary
to the original level is

(a) 20%
(b) 25%
(c) 33 1/3%
(d) 30%

• 33 1/3 %
  
  If initial salary is Rs 100.
  After 25% reduction, salary will become Rs 75.
  
  To make it again Rs 100, the salary should be increased by Rs 25.
  
  So % increase required = 100*25/75= 100/3 % = 33 1/3 %

• c) 33 1/3%
  
  Taking 100 Rs as salary
  
  Salary reduced by 25 % so salary is reduced 100 x 0.25 =25
  
  So present salary is 100-25 = 75 Rs.
  
  To take it Original value
  
  75 Rs = 100 (I take 75 as 100%)
  100 Rs =?
  
  100 x 100
  -----------
  75
  
  = 133.33 %
  
  Difference
  
  = 133.33-100 % = 33.33 % = 33 1/3%

• 75/100*x=100/100 ==>x=133/100===> 33% increase
  
  or
  
  25/(100-25)=1/3=33%.

• Super Short Cut for this type Ques.
  if reduced by n then increase by ( n-1)
  25% = 1/4 =1/n
  then 1/n-1 = 1/4-1 = 1/3 = 33 1/3 %

• 75+75*x/100=100
  solve it and get
  ans= 33 1/3 %

• Consider ravi's salary is RS:1000/- if it reduced by 25% then it will 750/-
  (750 = 1000-((25/100)*1000))
  
  To make it into original salary (750+((x/100)*750)=1000) by solving x = 33 1/3%.
  
  so, option (c)

• answer: Assume the salary of ravi be 100 rs
  it reduced by 25 percent ,thus it became = 75 rs
  
  now again the percent we need to increase to get 100 rs is
  [(100-75)/75] x 100 = 33.3 percent
  
  33 1/3%

• (c) 33 1/3%
  because 25% less means 100-25 = 75.
  so 25/75*100=33 1/3%

• answer is 33 1/3%
  100-25/100*100 = 75%
  75+33.3/100*75=100
  so answer is c

• we hv the short cut method i.e, (x/(100-x))*100
  so the answer will be (25/75)*100 i.e, 33.3333

• Let the salary of ravi be X. Now let us assume the salary of ravi is 75x. To get back to original salary we need 25x.
  Then, 25x/75x*100=33.33

• I had a shortcut for this problem
  for increase in every (1/n) th part, there must be a decrease in (1/n+1) th part to balance the percentage.
  In problem decreased by 25% i.e, (1/4) th so there must be an increase in (1/3) rd part it is 33.33% or 33 1/3

• 33.3 % to be incremented i.e., 33 1/3%

• formula for these type of questions:
  R/(100-R)*100 where R is the percentage decreased
  if in question R is increased percentage, then formula is as follows:
  R/(100+R)*100
  so using the first formula we get
  25/(100-25)*100=33.33%=33 1/3%
