if a:b=5:3,what percentage of 3a is (3a+4b)?

• a:b=5:3
  a is 5/5+3=5/8 part
  b is 3/5+3=3/8 part
  now,
  3a=>3*(5/8)
  =15/8
  4b=>4*(3/8)
  = 12/8
  now in question it is clearly said what percentage(let it be x) of 3a is (3a+4b)
  i.e. convert the given statement in mathematical form:-
  x% of 3a=(3a+4b)
  =>(x/100) of 3a=(15/8 + 12/8)
  =>(x/100)*(15/8)=27/8
  =>x=(27 * 100)/15
  = 9*20
  =180
  so, answer is 180%

  a:b=5:3, 3a=5b
  As 5b=3a, so 4b=12a/5
  (3a+4b)= 3a+(12a/5)=27a/5
  (3a+4b) as percentage of 3a= 100*(27a/5)/3a= 180

• 3a=5b;
  3a+4b=9b;
  percentage=(9b/5b)*100
  =180

• a:b=5:3,3a+4b=3*5+4*3=27
  let x% of 3a=27
  x100*15=27
  x=180

• let a=50 and b=30 then 3a=150 and 4b=120 so 3a+4b=270 now pecentage of 3a is 3a+4b=> 3a+4b/3a*100=270/150*100

• a:b =5:3
  3a:(3a+4b)
  3*5x:(3*5x+4*3xx)
  15x:27x
  5:9

• Since a:b is 5:3, so a=(5/3)b
  and 3a+4b as % of 3a will be
  ((3a/3a)+(4b/3(5/3)b) )*100
  i.e (1+0.8)*100=180%

• 3a+4b=> 3a+4b/3a*100=270/150*100

  a:b=5:3 ;
  3a=5b;
  b=12a/5 ;
  
  (27*100)/(5*3)

• (x/100)*3a=3a+4b
  x=(3a+4b)*100/3a
  a:b=5:3
  x=(3*5+4*3)*100/3*5
  Solving this we get
  x=180%

• just assume a=5 b=3
  solve you will get 100*27/15 =180%

• b:a=3:5
  (3a+4b)/3a=1+4b/3a
  substituting the vale of b:a in above equation we get
  (9/5)*100=180

• a= 5/5+3 b = 3/3+5, >> a = 5/8 ,, b = 3/8
  3a= 15/8 , 4b = 12/8
  x/100*15/8 = 15/8 + 12/8
  x/100 = 27 *100
  x = 27 *100/15
  x = 180 ......................
