A grocer mixes 3 varieties of Dal costing him RS.25, RS.30, RS.33 respectively per kg in the ratio of 1 : 2 : 5. He decides to sell the mixture at RS.35 per kg. Another grocer mixes the three varieties of Dal in equal proportions and sells the mixture at RS.35 per kg. If RS.350 is spent and equal quantities of both the mixtures are bought, then find the ratio of the three varieties respectively, if all that is bought is mixed up.
ooption
a) 11 : 14 : 23
b) 8 : 6 : 15
c) 1 : 1 : 1
d) 1 : 2 : 4

for grocer1 the quantity of items are (1/(1+2+5)),(2/(1+2+5)),(5/(1+2+5)).
for 2nd grocer the quantity of items are(1/(1+1+1)),(1/(1+1+1)),(1/(1+1+1)).
now these are mixed.
so the ratios of quantities are (1/8 + 1/3):(2/8 + 1/3):(5/8 + 1/3)=11:14:23
