Raman's salary was decreased by 50% and susequently increased by 50%. He has a loss of :

a. 0%
b. 25%
c. 0.25%
d. 2.5%

• let his salary be 100
  dec by 50%-> 50(50%of 100=50,hence 100-50 for dec)
  inc by 50%-> 75(50%of 50=25,hence 50 +25=75)
  over all loss of 100-75=25%

• first take salary is 100%
  100-50/100*100 = 50%
  50+50/100*50 = 75%
  so 100-75=25%
  so decrease is 25%

• we can solve this question by formula A+B+(A*B)/100...NOTE:-When decreases take -ve .
  so ,(-50)+50+((-50)*50)/100=-25(i.e loss of 25%)
  so,25% (ANSWER)

• ans: 25%
  we hv the formula if m% and n% increased subsequently then the total increased percent is: m+n+(mn/100). the signs are given with respect to increament or decreament i.e, if m% of increament is there &n% of decreament is there then (m-n+(m*-n/100)
  Here 50-50-(50*-50/100)=-25% so the loss is 25%

• You can directly use the formula= x^2/100
  if there is x% profit and x% loss
  
  =50^2/100
  =50*50/100
  =2500/100
  =25%
