B's monthly salary is less by 10% than that of A's.C's monthly salary is less by 25% than that of A's.By what percent of B's salary more than that of c's?

• 15%
  let us consider a salary is 100
  b salary =90
  c salary=75
  if we consider c salary 75 is 100%
  b salary is more than c is 15
  75----100%
  15------?%
  15/75*100
  20%

• ans : 20%
  B's salary = 90/100 * A's salary ---(1)
  C's salary = 75/100 * A's salary
  ===> A's salary = 100/75 * C's salary
  
  substituting in (1)
  B's salary = 90/100 * 100/75 * C's salary
  = 120/100 * C's salary

• if ans is 15 % its absolutely wrong.
  why,
  asked in question was "By what percent of B's salary more than that of c's".
  
  But you are doing with respect to A. Doing with respect to B is write one.

• let a salary is 100.
  then b=90,and c=75.
  b salay is 15 more then c.
  %=(15*100)/75=20% ans.

• ANS is 15%
  Let A's salary=100%
  Given B's salary=10%less than A so B=90%
  lly C=75%
  So, B's salary is 15% more than c

• B's salary is 10% less than that of A's,
  means
  B's salary is 90% of A
  similarly
  C's salary is less by 25% than that of A
  means
  C's salary is 75% of A
  Therefore
  B's salary is 15% more than that of C's

• let A's salary=x then B's salary will be x-10% of x and C's salary will be x-25% of x.now given that B's salary is more than C.so,subtract C's salary from B's salary it will be 3x/20 then find how much percent 3x/20 will make from B's salary
  
  ANS:50/3%--->16 and 2/3%

• ans: According to problem
  initially lets we assume a=100%..now from the problem..
  A B C
  100% 90% 75%
  15/75*100=20%

• let c's salary is 100
  b's will be 90
  c's will be 100(1-25/100)=100*(75/100)=75
  [(90-75)/75]*100=(15/75)*100=20%

• RATIO of B:A = 9:10
  RATIO of C:A = 3:4 (MULTIPLYING FACTOR APPROACH)
  
  NOW, equate the ratio,
  A:B:C = 40:36:30
  
  B is 6 MORE THAN C.
  SO, 6/30*100= 20%
