Question 261066


Let the quantity of peanuts to be mixed =x
Almonds will be 2x
Let the cashew nuts mixed be y

3x+4*2x+8y=140*6=840
11x+8y=840 ---------1
3x+y= 140------------2

Multiply eq2 by 8 and subtract from 1

24x+8y=1120


11x+8y=840 
24x+8y=1120

-13x= -280
X=280/13  
=21.54  = peanuts

2x= 43.08 =almonds

Y=75.38 = cashew nuts
