A solution of 80 litres contains oil and water in the ratio 10:x. If five litres of water is added to the solution, the ratio becomes 20:10, find the value of x?	Choose the correct choice from the following:
A) 4.1
B) 4.9
C) 4.7
D) 5.7
E) 8.5
Exp. Total new quantity = original sol + water =80+5= 
<gadget id="calculator">80+5</gadget>
<output>85</output>
85   New ratio= 20:10, New quantity of oil =20/30*85 = 56.6 Lit,   New quantity of water = 10/30*85 =28.3 Lit   Water present initially = (28.3-5)= 
<gadget id="calculator">(28.3-5)</gadget>
<output>23.3</output>
23.3 Lit   Ratio= 56.6/23.3 =10/x There for x = 4.11   4.1nswer: 4.1
