Jim, Carla and Tomy are members of the same family. Carla is 5 years older than Jim. Tomy is 6 years older than Carla. The sum of their 3 ages is 31 years. How old is each one of them?

Answers

let the age of jim be x
carla's age= x+5
tomy's age= 6+5+x
sum of their ages=31
x+x+5+x+5+6=3x+16=31
3x=31-16
=15
x=15 divided by 3
= 5
jim's age=5
carla's age=10
tomy's age = 16

x - Jim
y - Carla
z - Tomy

$y=x+5\n z=y+6\n x+y+z=31\n\n x=y-5\n z=y+6\n x+y+z=31\n\n y-5+y+y+6=31\n 3y=30\n y=10\n\n x=10-5\n x=5\n\n z=10+6\n z=16$

if employee a logged 120 hours of travel in four years and employee b logged hours of travel at a 20% higher rate, how many more hours did employee b have than employee a after 1.5 years

Answers

Traveled hours by a in four years = 120
Traveled hours by b in four years = (120/100) * 120
= 144
Excessive hours traveled by b in 4 years = 144 - 120
= 24
Excessive hours traveled by b in 1.5 years = (24/4) * 1.5
= 9 hours
