c) 44 yrs
d) 45 yrs
e) 48 yrs ​

Answer 1

Answer:

a) option is correct

Step-by-step explanation:

let ganesh age is x years,

so suresh present age is 1 (2/3) of x => => 5x/3,

ramesh age is same as of his father suresh when ramesh born..

it means ramesh age is half of his father(suresh) age now..

so

suresh present age is 5x/3

ramesh age is (5x/3)/2 => => 5x/6

present age of ganesh is x+5x/3 =>=>8x/3 ( when suresh born ganesh is x, suresh age is 0.. now suresh age is 5x/3)

average of ramesh and ganesh => => (5x/6)+(8x/3)=42*2

5x+16x=42*2*6

21x=42*2*6

x=24

present age of suresh is 5x/3 =>=> 5*24/3 =>=> 40

suresh present age is 40 years..
