Answer 1

Step-by-step explanation:

6 years ago, the ratio of the ages of Arun and Prathap is 7: 6. Present age of Rajeev is 10 years more than one – sixth of Prathap’s present age. Find the ratio of present age of Prathap and Rajeev, if Arun’s age after 6 years is 40 years?

Answer 2

Answer:

2:1

Step-by-step explanation:

6 years ago, the ratio of the ages of Arun and Prathap = 7: 6 (7x, 6x)

Present ages of Arun and Prathap = 7x + 6, 6x + 6

Present age of Rajeev = (1/6)*Prathap’s present age + 10

Arun’s present age = 40-6years=34 years

According to the question,

7x = 28

x = 4

Prathap’s present age = 6x + 6 = 30

Rajeev’s present age = (1/6)*30 + 10 = 15

Required ratio = 30: 15 = 2: 1
