the age of rahul and harun is 5:7. After four years, Sum of their age is 56. What is their present age?

20 and 28

Step-by-step explanation:

r/h= 5/7  ⇒ r= 5/7h

r+4+h+4= 56

r+h= 48

5/7h+h= 48

12/7h=48

h= 28

r= 48-h= 20

Rahul is 20, Harun is 28

99

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
