Question

Age of hari and Harry are in ratio of 3:4 after five years sum of their present age is 45 find present ages​

Answer 1

Step-by-step explanation:

Let the age of hari and Harry be 3x and 4x respectively

now,

After five years the sum of their age is 45

(3x+5) + (4x+5) = 45

7x + 10 = 45

7x = 45-10

7x = 35

x = 5

therefore,

The age of hari = 3×5 = 15

age of Harry = 4×5 = 20

Answer 2

Let Hari's age be 3x and harry's age be 4x

after five years:

Hari's age:  3x+5

Harry's age: 4x+5

ATQ:

(3x+5) + (4x+5) = 45

              7x+10 = 45

                    7x = 45-10

                    7x = 35

                      x = 35/7

                       x=5

hari's age : 3x= 3×5= 15 yrs

harry's age : 4x = 4×5 = 20 yrs
