a) 2 litres
b) 3 litres
c) 2.5 litres
d) 5 litres
Answer: c
Explanation: 20 litres juice contain 10% Tomato, i.e.
20L juice = $$\frac{{20 \times 10}}{{100}}$$ = 2L Tomato
Tomato puree contains 80% of water and 20% tomato.
This 80% tomato = 2L (which is contained by 100 puree)
Now this 2 L Consist 80% in puree
Total puree will be $$\frac{2}{{0.8}} = 2.5{\text{L}}$$
