Question 9:

In a cricket team of 11 players,the average age of 4 players is 17,the average of 3 players is 18 and the average of 2 players is 19. The average age of the whole team is 18. One of the players is aged 22. Find the age of the last player.

Solution:

Average of 11 players = 18 years

Total age of 11 players = 18 x 11

= 198

Average of 4 players = 17 years

Total age of 4 players = 4 x 17

= 68

Average of 3 players = 18 years

Total age of 3 players = 3 x 18

= 54

Average of 2 players = 19 years

Total age of 2 players = 2 x 19

= 38

Age of another player = 22 years

Total age of 10 players = 68 + 54 + 38 + 22

= 182 years

Age of last player = 198 - 182

= 16 years

Therefore the required age = 16 years.

Question 10:

A fruit merchant bought 1200 mangoes for \$1000.300 fruits went bad. He sold fruits at \$ 18 per dozen, and the bad fruits at \$ 9 per dozen. Find his total gain or loss per cent in the transaction.

Cost price of the mangoes = \$ 1000

Number of good fruits = 900

Number of dozens of good fruit = 900/12

= 75 dozens

Selling price of 1 dozen = \$ 18

Selling price of 75 dozens = 75 x 18

= 1350

Number of bad fruits = 300

Number of dozens of bad fruits = 300/12

= 25

Selling price of 1 dozen bad fruit = \$9

Selling price of 25 dozens of bad fruits = 9 x 25

= \$ 225

Total selling price = 1350 + 225

= \$ 1575

Profit = Selling price - Cost price

= 1575 - 1000

= \$ 575

Profit percent = (profit amount/cost price)   x 100

= (575/1000) x 100

= 57.5 %
