Question

5 yrs ago the average age of Rashi and Saurabh was 20 yrs. now the average age of Rashi, Saurabh and Misha is 30yrs. what will be the age of Misha after 15 yrs?? ​

Answer 1

Answer:

age of Misha is 55 years

Step-by-step explanation:

let assume present age of Rashi is x , Saurabh is y, Misha is z

5 years ago average age of Rashi and Saurabh is 20 yrs

=> (x-5)+(y-5)/2=20

=>x+y-10=40

=>x+y=50

now present average age of Rashi, Saurabh and Misha is 30yrs

then (x+y+z)/3=30

=> (x+y+z)=90

but we know x+y=50

=>30+z=90

z=40

current age of Misha =40

age of her after 15 yrs = 40+15=55 yrs

I HOPE ANSWER IS HELPFUL....
