(b) 30,50

(d) 60,30​

Answer 1

Answer:

Given :

• Ram is twice as old as Rama
• Let take Ram age as 2y (Present age)
• Rama age as y (present age)
• After 10 years, Ram will be 30 years more than Rama

Find :

• Present age of Ram & Rama

Solution :

From the question,

After 10years, Ram will be 30 years more than Rama So, 2y = 30 + y

Let's solve this :

⇒ 2y = 30 + y

⇒ -y + 2y = 30

⇒ y = 30

Rama age = y = 30

Ram age = 2y = 2 × 30 = 60

Therefore,

• Present age of Ram = 60
• Present age of Rama = 30

Step-by-step explanation:

Given :

Ram is twice as old as Rama

Let take Ram age as 2y (Present age)

Rama age as y (present age)

After 10 years, Ram will be 30 years more than Rama

Find :

Present age of Ram & Rama

Solution :

From the question,

After 10years, Ram will be 30 years more than Rama So, 2y = 30 + y

Let's solve this :

⇒ 2y = 30 + y

⇒ -y + 2y = 30

⇒ y = 30

Rama age = y = 30

Ram age = 2y = 2 × 30 = 60

Therefore,

Present age of Ram = 60

Present age of Rama = 30
