1.	Three years ago , the ratio of ages of ravi and siva was 14 : 1 .After three years from now , the ratio of their ages will be 8 : 1 . What is the differnce between their ages after 10 years from now .
Answer» Step-by-step explanation: The ratio of Hari's and Harry's PRESENT ages is 5:7 So, let their ages be 5x and 7x After 4 years their ages will be in ratio 3:4 Therefore,(5x+4)/(7x+4)=3/4 or, 4(5x+4)=3(7x+4) or, 20x+16=21x+12 or, 16−12=21x−20x or, 4=1x or, x=4 Therefore, present AGE of Hari = 5x=(5×4)=20 years. Present age of Harry =7x=(7×4)=28 years The sum of their age is 28+20=48years

Answer»

Step-by-step explanation:

The ratio of Hari's and Harry's PRESENT ages is 5:7

So, let their ages be 5x and 7x

After 4 years their ages will be in ratio 3:4

Therefore,(5x+4)/(7x+4)=3/4

or, 4(5x+4)=3(7x+4)

or, 20x+16=21x+12

or, 16−12=21x−20x

or, 4=1x

or, x=4

Therefore, present AGE of Hari = 5x=(5×4)=20 years.

Present age of Harry =7x=(7×4)=28 years

The sum of their age is 28+20=48years
