Answer» Answer: Let us CONSIDER the age of the father x and the SUM of AGES of the 5 children as y. At present, x=y−−−−(i) After 15 years, Father’s age = x + 15 Sum of children’s ages = y + 5*15 (Because in the course of 15 years, each child will grow by 15 years) x+15=1/2(y+5∗15)−−−−(ii) Solving (i) and (ii), we get by substituting the value of x from (i) in (ii) y+15=1/2(y+5∗15) =>2y+30=y+75 => y=45 which implies, x = 45 The age of the father is 45 year old please MARK as brainliest answer |
