Question

Pls answer of this question ​

Answer 1

Step-by-step explanation:

Let Rani's age be x

Then Arjun's age = 2x

5 years ago, Arjun was thrice as old as Rani

So,

2x - 3 = 3(x-3)

2x - 3 = 3x - 9

x = 6

Rani's present age is 6

Arjun's present age is two times Rani's age so 6 × 2 = 12

Answer 2

Answer:

Let's take Rani's age as x yrs. Therefore, according to the question, Arjun's age is 2x years.

Given, five years ago, Arjun's age was three times Rani's age at that time.

So five years ago, Rani's age = (x-5) years

Arjun's age would have been (2x- 5) years

According to the condition,

2x- 5= 3(x- 5)

⇒ 2x- 5= 3x- 15

⇒ x= 10

Therefore, Rani's current age is 10 years. Arjun is 20.

Verification: 5 years ago, Rani would be 5 years old and Arjun would be 15.

15= 3× 5, therefore the answer is right.

[ The verification part should not be added in the actual working but it should always be done as rough work to check the answer. ]
