Read Solution (Total 8)
-
- Mix x:y
cp=50x+60y
Sp=(50x+60y)+(50x+60y)*20/100
So,(50x+ 60y)+(50x+60y) *20/100=70(x+y)
x:y=1:5 - 10 years agoHelpfull: Yes(27) No(1)
- Ans:- 1:5
60-(350/6):(350/6)-50
- 10 years agoHelpfull: Yes(7) No(1)
- cp of mixture sold by eesha=350/6
using concept of allegation
50 60
350/6
10/6 50/6
therefore
ratio=1:5 - 10 years agoHelpfull: Yes(7) No(0)
- 120/100*x=70;
x=58.3333
ratio=60-58.3333/58.3333-50=1.666/8.33333=1/5=1:5 - 10 years agoHelpfull: Yes(4) No(0)
- 60*x + 70*y = 70*x +70*y ,
So, x/y= 1/5. - 10 years agoHelpfull: Yes(3) No(1)
- c.p= 100*70/120= 175/3
the ratio= (175/3-50):(50-175/3) i.e1:5 - 10 years agoHelpfull: Yes(2) No(1)
- mean price(Cost price of 1 kg of mixture)= 100*70/120=175/3
Now,
50 60
/
175/3
/
(60-175/3) :(175/3-50) =5/3:25/3 = 1:5
So 1:5 is the answer. - 10 years agoHelpfull: Yes(2) No(0)
- ratio of mixture is 1:2
- 10 years agoHelpfull: Yes(0) No(3)
