Question
Shivani is 6 years younger than Deepika and Deepika is 6
years younger than Mohani. After 6 years the ratio of Shivani’s age and Mohani’s age will be 5:7 individually,then what will be the present age of DeepikaSolution
ATQ, We can say that the present age of Mohani is = ‘m’ years Then, the Present age of Deepika is = (m – 6) years So, the Present age of Shivani is = (m – 12) years (m - 6)/(m + 6) = 5/7 7m – 42 = 5m + 30 7m – 5m = 30 + 42 2m = 72 m = 36 So, present age Deepika is = (m - 6) = (36 - 6) = 30 yrs.
