Busy Life Of Santa Claus!

let the working life of santa be 'x' years...x=(x/3+x/4+x/5)+13. from this equation, we get x=60. as santa started working at 15, his age will be 15+60=75.

Call x = Santa's working years, we have:

$\frac{1}{4}x + \frac{1}{5}x + \frac{1}{3}x + 13 = x$ $\frac{47}{60}x + 13 = x$ $13 = \frac{13}{60}x$ $x = 60$

so, Santa's age equal to: 15 + x <=> 15 + 60 = 75

let the age of santa = y
let the working life of santa = x
So
y=x+15 .............(1)
x=(x/3)+(x/4)+(x/5)+13.................(2)

solve equation no. 2
x=60
subsitute this value of x in equation no.1
y=(60)+15
y=75
therefor age of santa = 75

1/4+1/5+1/3=47/60 remaining = 13/60, so working life = 60, so total age=60+15=75

4times5times3=60 60+15=75

The total time spent by Santa in working = x.
Therefore, x = x/3 + x/4 + x/5 + 13.
Therefore, x=60.
Thus, Santa's total age = 60+15 =75.
Ans: 75 years.

(1/4 + 1/5 +1/3)*60 + 15+28=75

75 years old

Let $x$ be the working life of Santa in years. Then he spent,

$\frac{x}{4}$ of his working life in the factory, $\frac{x}{5}$ of his working life in the office & $\frac{x}{3}$ of his working life as a caretaker. And for the last $13$ years of his working life, he had been Santa. So we get the following equation :

$\frac{x}{4} + \frac{x}{5} + \frac{x}{3} = x - 13$

Solving this, we get $x = 60$ .

But he started working at the age of $15$ years.

$\Rightarrow$ His age is $15 +$ his working life.

$\Rightarrow$ $15 + 60 = \boxed{75}$ .

Add up the fractional work experience and subtract from one to determine the fractional work experience as a Santa

i.e. $\frac{13}{ 1 - \frac{1}{4} + \frac{1}{5} + \frac{1}{5} }$

$\Rightarrow \frac{13}{\frac{13}{60}} = 60$

So his age is 60 + 15 = 75

x=(x/3+x/4+x/5), we get x is 60 and 60+15=75

say,his total working life is x years.so (x\4)+(x\5)+(x\3)+13=X.then X=60.so he is 60+15=75 years old.

say,his total working life is x years.so (x\4)+(x\5)+(x\3)+13=X.then X=60.so he is 60+15=75 years old.

x = x/4 + x/5 + x/3 + 13, so x = 60.. then 60 + 15 = 75!!!

take the L.C.M of 4,5,3 and add 15 to it answer will be 60+15=75

Let x be the total working age. Then: 1/5x + 1/4x + 1/3x + 13 = x => x =60 He worked since he was 15 So total age =(60+15) = 75 years.

Age = 15 + (x/4 + x/5 + x/3 + 13)

or

Age = 15 + x

where x = Working Life

x = x/4 + x/5 + x/3 + 13

x = 9x/20 + x/3 +13

x = 47x/60 + 13

x - 47x/60 = (47x/60 - 47x/60) + 13

13x/60 = 0 + 13

13x/60 = 13

(13x/60) * 60 = 13 * 60

13x = 13 * 60

13x/13 = (13 * 60)/13

x = 1 * 60

x = 60

Age = 15 + 60

Age = 75

in the question the santa's age is show as 1.So we get the 1 as santa age. his work started age 15. the age from he did't work 13. 1=(1÷3,1÷4,1÷5)+13 from this we get 1=60 we get all ages except 15 so we add the work start age 60+15=75 So 1=75.So santa's age is 75 :)

let the working age of santa be X. Then his present age would be X+15. So, let's calculate his working age, i.e, X/4 + X/5 + X/3 + 13 = X => X=60. So, his present age = X+15=60+15=75.

let the age of the santa clause be x now, (x-15)=(x-15)/4+(x-15)/5+(x-15)/3 +13 implies that,x=75 years

let age of santa is=x,then x=x/4+x/5+x/3,we get x=60.hence his age will be=working age+15,which is =75.

here , let x/4 life in factory , x/5 in other and x/3 in any other so adding this we get 47x/60 so 47 years in all these works and 13 years as santa and 15 years as child so 15+13+47=75 years..that's it

Let x be the working life so (1/4)x + (1/5)x + (1/3)x + 13 = x. Solve and eventually you will get 13x = 780. Solving this you will get x = 60. Then add 15 and you will get age as 75.

get the L.C.M of the 3 values 4,5,3 which are the denominators of the fractions the answer will be 60 hence we get the fractions 15/60, 20/60 , 12/60 add these fractions : 47 / 60 subtract from 1 the above fraction now we form an algebric equation: 13/ 60 * (X-15) = 13

1/4 + 1/5 + 1/5 = 47/60 , Since the last 13 years of his life represent 13/60, Therefore, his working life= 47 + 13= 60. Therefore, his age= 15 + 60=75 years #

consider total working life as x..........find solution and add 15 to know his age

(1-(1/4+1/5+1/3))*X = 13

X=13/(1-(47/60))

X= 13/(13/60)

X=60

work life = 60

Age = work life + age during start of work Age= 60+15 Age =75

Let Santa's work Life be x. Then x=(1/3+1/4+1/5). The answer in decimal form is 0.78. so he spent 78% of his life as working in Factory,Office and as School caretaker. Now the remaining working life is 22%. We know that he spent 13 years of his remaining working life as SANTA. so 22% of x is equal to 13. Thus we get x=60. Now since he started working at 15. His age would be x+15 that is 60+15= 75. This is how i got to the answer.(There is a small error in the question that x =59.09. If we round off it it becomes 59. thus 59+15=74. So the correct answer should have been 74)

1/4 + 1/5 + 1/3 = 13/60 remaining years = 1/1 – 13/60 = 13/60 so 13/60 part = 13 years then 1 part = 60/13 × 13 = 60

age = 15 + 60 = 75 years

Let total age of Santa be x, 15 years no work. So Working Life = x-15.

Equation is - 15 + 13 + (x-15)/4 + (x-15)/5 + (x-15)/3 = x

let the age of santa=x; then his working age=(x-15); so, (x-15)=((x-15)/3+ (x-15)/4+(x-15)/5)+13; from this we get x=75; therefore age of the santa is75

Let the total working life is 'x' As per x-(x/3+x/4+x/5)=13 we can find x=60 Total life will be, 15+60 = 75

1/3 +1/4 +1/5 =47/60

So, he has spent 13 years of his working life to be Santa Claus

60/60 - 47/60 = 13/60

1 year=1/60

60years=60/60 60years+15years=75 years

Let X be his working life...

First, you have to find the value of X and it will be possible if you deduct the WHOLE WORKING life with the given Fraction giving a remaining working life which is 13

Illustration:

X - (47/60)(X) = 13 (13/60)(X) = 13 X = 60

Then, to get his present age, add his working life with his age when he started working

15 + 60 = 75 ;)

Started working at 15 yrs of age, suppose age is X yrs add X-15/4 + x-15/5 + X-15/3 + 15 +13 will be equal to X simplifying above we get 75 yrs Ans

Assume that his working life is $x$ years.

Now from the question we can derive the equation that,

$x\frac{1}{4}+x\frac{1}{5}+x\frac{1}{3}+13=x$

from this equation we find the value of $x$ is $60$

He started the job at the age of $15$ , so he is $75$ .

let the working life of Santa is x. so the equations becomes x= x/3+x/4+x/5 comes out to be 60. than simply add 15 to it.
