it's urgent frnds please help me ..​

Answer 1

Answer:

50 years of age

Step-by-step explanation:

Let the man's current age=x

Therefore,

The man's age ten years ago=x-10

The man's age in 10 years=x+10

83$\frac{1}{3}$ %=5/6

Set up an equation to solve for his age:

1.25(x-10)=(5/6)(x+10)

1.25x-12.5=(5/6)(x)+25/3

(1.25x-12.5)-(5/6)(x)=((5/6)(x)+25/3)-(5/6)(x)

1.25x-(5/6)(x)-12.5=25/3

Convert all decimals to fractions to make the math easier, and continue solving for x:

(5/4)(x)-(5/6)(x)-25/2=25/3

((5/4)(x)-(5/6)(x)-25/2)+25/2=25/3+25/2

(5/4)(x)-(5/6)(x)=50/6+75/6

(15/12)(x)-(10/12)(x)=125/6

(5/12)(x)=125/6

(12/5)(5/12)(x)=(125/6)(12/5)

x=50
