plz answer briefly ​

Answer 1

5. Set Radha's age is A -> 3.A + 5 = 50 -> 3A=45 -> A=15

6.Set K's score is A -> 3A+A=200->A=50

Answer 2

Answer:

5) $\boxed{\bold{15 \;years}}$  

6)Kohli's score = $\boxed{\bold{50}}$

  Rahul's score = $\boxed{\bold{150}}$

Step-by-step explanation:

Questions:

5) Radha's father's age is 5 years more than three times Radha's age.Radha's father is 50 years old. Set up equations to find Radha's age.

6) Rahul's score is thrice as score as Kohli. Together their score is double century. How many runs did each score?

To Find:

5) Radha's age = ??

6) Runs scored by each = ?

$\boxed{\boxed{\bold{Solution:}}}$

5) Let Radha's age be x

 According to the Question,

5 + 3x = 50

⇒3x = 50 - 5

⇒3x = 45

⇒x = 45 ÷ 3

⇒x = 15

∴ Radha's age = $\boxed{\bold{15 \;years}}$  

6) Let Kohli's score = x

  ⇒Rahul's score = 3x

 According to the Question,

x + 3x = 2× 100

⇒4x =200

⇒x = 200÷4

⇒x= 50

⇔Kohli's score = x = $\boxed{\bold{50}}$

⇔Rahul's score = 3x = 3 × 50 = $\boxed{\bold{150}}$
