Question

A mixture of mango juice and water of 30 liters contains 80% mango juice. X liters of water must be added to this mixture to raise the percentage of water to 25%. Find X?

  • 8
  • 6
  • 4
  • 2
Answer- D

Water in the given mixture = 20*30/100 = 6 litre,

And mango juice = (30-6) = 24 litre

Let x litres of water added, Then, x+6/30+x *100 = 25

x+6/30+x = 1/4

4x+24 = 30+x

3x =6

x = 2 litre
