Question

In a Rugby team of 15 players, the average age of players is 19 years.

If one more player is added in the team, the average is increased to 22 years.

What is the age of this new player?

Answer 1

The ratio of Rs.1, 50 paise and 25 paise coins is 5:6:8

∴ Number of Rs.1 coins = 5x.

⇒ Number of 50paise coins = 6x

⇒ Number of 25paise coins = 8x.

∴ Value of 5x Rs.1 coins = Rs.1×5x=Rs.5x.

⇒ Value of 6x 50paise coins = 6x×50paise=Rs.

100

6x×50

=Rs.3x

⇒ Value of 8x 25paise coins = 8x×25paise=Rs.

100

8×25

=Rs.2x

⇒ Total amount = Rs.420

∴ 5x+3x+2x=420

∴ 10x=420

∴ x=

10

420

=42

∴ Number of Rs.1 coins = 5×42=210

∴ Number of 50paise coins = 6×42=252

∴ Number of 25paise coins = 8×42=336

⇒ Total number of coins = 210+252+336=798

Answer 2

285+ x = 352

new age = 67

hope you got your answer
