Avor: Blinkov A.d:

Sasha and Vanya were born on March 19. Each of them celebrates their birthday with a cake with candles equal to the number of years they have turned. In the year they met, Sasha had as many candles on his cake as Vanya has today. It is known that the total number of candles on the four cakes of Vanya and Sasha (then and now) is 216. How old is Vanya today?
If we transfer the "extra" candles from today's Sasha's cake to the old Vanya's cake, we will get four cakes with the same number of candles. This means that today Vanya turned $216: 4=54$ years old.

## Answer

54 years old.
