A solution of 90 litres contains milk and water in the ratio 7:x. If ten litres of water is added to the solution, the ratio becomes 3:2, find the value of x? Pick one: A) 2 B) 1.5 C) 3.5 D) 2.5 E) 3
Exp. Total new quantity = original sol + water =90+10=

100   New ratio= 3:2, New quantity of milk =3/5*100=

<output>60</output>
60 Lit,   New quantity of water= 2/5*100= 
<gadget id="calculator">2/5*100</gadget>
<output>40</output>
40 Lit   Water present initially= (40-10)=

<output>30</output>
30 Lit   Ratio= 60/30 =7/x There for x = 3.5   Answer: 3.5
