Question

In an Unnamed grocery store, the manager mixed eight kgs of salt worth Rs. 16 per kg is mixed with four kgs of salt worth Rs. 22 per kg. What is the mean price of the mixture?

  • 20
  • 19
  • 17
  • 18
Answer- D

P1 = Rs.16 per kg, p2 = Rs. 22 per kg, q1 = 8 kg, q2 = 4 kg

Now , p = (p1q1+p2q2)/(q1+q2)

Average price of the mixture

= (8*16+4*22)/(12) = 128+88/12 = 216 /12 = 18
