Three types of wheat of Rs. 1.27, Rs. 1.29 and Rs. 1.32 per kg are mixed together to be sold at Rs. 1.30 per kg. In what ratio should this wheat be mixed?
Answer & Solution
Correct Answer:
Option
D
Average cost: Rs. 1.30 per kg.
And,
Hence, ratio of 1.27, 1.29 and 1.32
⇒ n1 : n2 : n3 = 2 : (2 × 3) : 3 ⇒ n1 : n2 : n3 = 2 : 6 : 3
And,
Hence, ratio of 1.27, 1.29 and 1.32⇒ n1 : n2 : n3 = 2 : (2 × 3) : 3 ⇒ n1 : n2 : n3 = 2 : 6 : 3

Login= n1:n2:n3= 2:2:(3+1)
n1:n2:n3= 1:1:2
1.29-1.30=-0.01
1.32-1.30=+0.02
(-0.03*1)+(-0.01*1)+(0.02*2)=0
Then ratio of 1.27,1.29 & 1.32 is
1:1:2 right answer
