Question

eesha bought two varities of rice costing 50rs per kg and 60 rs per kg and mixed them in some ratio.then she sold that mixture at 70 rs per kg making a profit of 20 % what was the ratio of the mixture? a)1:

Answer 1

HELLO DEAR,

let x be the price of the rice after mixing,

then,

120 * x/100 = 70

x = 70*100/120

x = 700/12

x = 175/3

NOW, by eligation method

the required ratio is

(60 - 175/3) / (175/3 - 50)

{(180 - 175)/3} / {(175 - 150)/3}

(5/3) / (25/3)

5/25

1/5 = 1 : 5

HENCE, the required ratio is 1 : 5

I HOPE ITS HELP YOU DEAR,

THANKS
