Question

The sum of present ages of Sarthak and Sumeet is 25 years. Four years ago, Sumeet's age was 3 years less than Sarthak's age at that time. Find their present ages.
​

Answer 1

Answer:

present age of sarthak = x years ⇒   14 years  

present age of summeet = y years⇒    11 years

Step-by-step explanation:

let the present age of sarthak = x years

let the present age of summeet = y years

according to question,

    x + y = 25                 ⇒  x = 25 -y                        ......(1)

four years later ,

y + 4 =  x + 4 - 3

y + 4 =  x + 1

y + 4 =  25 -y + 1                                  [ using ...(1) ]

y + y = 26 - 4

2y = 22

y = 11

now ,       x = 25 -y            ⇒    25 - 11

x = 14

present age of sarthak = x years ⇒   14 years  

present age of summeet = y years⇒    11 years
