Answer 1

Rickey age is r

so vickey age would be 3r

after 5 years ,

Rickey age would be 5+r

vickey age would be 3r+5

Sum of their ages is

(5+r) + (3r+5)

= 5+r+3r+5

= 10+4r

hence the answer is option a.

~ According to the question as we already know that what is given or what to determine. Let's see what to do..!

◕ Vickey is 3 times as old as Rickey. (Given)

◕ Rickey age is r year's (Given)

Henceforth,

◕ 3r years is the age of Vickey. (Finded)

◕ Sum of their age after 5 year's (To determine)

After 5 year's

•↝ Age of Rickey = (r+5) years

•↝ Age of Vickey = (3r+5) years

Sum of their age after 5 years

•↝ Age of Rickey + Age of Vickey

•↝ (r+5) + (3r+5)

•↝ r+5 + 3r+5

•↝ r+3r+5+5

•↝ 4r + 10 years
