Question

Tio of syrup and water in 72 litre of a cold drink is 7:2.the amount of water you need to pour for making the ratio of syrup and water as 4:3 is option (a)62 litre,(b)26 litre,(c)52 litre and (d)25 litre

Answer 1

Answer:

26 litres

Step-by-step explanation:

initial ratio = 7:2

quantity of water in initial solution = 2/(7+2) *72=(2/9)*72= 16 litre

quantity of syrup in initial solution = 7/(7+2) *72=(7/9)*72= 56 litre

if x amount of water  is added, the ratio should become 4:3

56/(16+x)= 4/3

cross multiply

4(16+x) = 56*3

64 +4x= 168

4x= 104

x= 26
