Question

Two years ago, the average age of Antonio, Brutus, and Caesar was 24 years and that of Brutus and Caesar 7 years ago was 25 years. Antonio's present age is?​

Answer 1

Answer:

14 years.

Step-by-step explanation:

26

2 years ago

Average= 24

Sum= 24×3= 72

7 years ago

Average age of Brutus and Caesar= 25

Sum= 25×2= 50

After 7 years

25+7=32(New Mean)

Sum=32×2=64(of Brutus and Caesar)

After 2 years

24+2=26(New Mean)

Sum=26×3=78( including Antonio's present age)

Antonio's present age= 78 - 64= 14 years

Verification:

Average= 78÷ 3

=26(24+2(Mean)).
