Question

Rani will be twice Raja’s age in $3$ years when Raja will be $40$. How many years old is Rani now?

• A. $20$
• B. $80$
• C. $77$
• D. $37$

Answer 1

Answer: C

Let’s say Present age of Rani = x years

Present age of Raja = y years

“Rani will be twice Raja’s age in 3 yeas when Raja will be 40” that means AFTER 3 years,

x+3 = 2(y+3)

given: y+3=40.

So, x+3= 80

x=77.
