- 60
Ratio of mixing =2x: x, Total quantity=50*2x+80*x=180x
Average price=180x/(2x+x)=60 - 11 years agoHelpfull: Yes(39) No(0)
- avg.price is 60

- let take 50 rs 2kgs then will result in 100rs
similarly 80rs 1kg---------------------80
total 100+80=180
180/3=60 - 11 years agoHelpfull: Yes(5) No(0)
- 2/3*50 + 1/3*80
= 60 - 11 years agoHelpfull: Yes(3) No(0)
- let avg price of rice is @ Rs X/-
then,
80-x/x-50=2/1
80-x=2(x-50)
80-x=2x-100
x+2x=80+100
3x=180
x=60 /-
ans is @ Rs 60/-.

- let x be the average price
according to alligations and mixtures formula
(2/1)=(80-x)/(x-50)
3x=180
x=60
