Question

Seema is 10 years elder than rekha. The ratio of their ages is 5:3. Find their ages

Answer 1

Answer:

seema is 25years old and rekha is 15 years old

Step-by-step explanation:

let rekha's age be x

so seema's age will be x+10

x + 10/x=5/3

3x +30=5x

3x-5x=-30

-2x=-30

x=15

so x+10=15+10=25

may these help you

$\huge\boxed{\fcolorbox{cyan}{grey}{Solution:-}}$.

➡Given here.

↪Let,

♠ Age of seema = X.

♠ Age of Rekha. = Y.

➡According to Questions.

↪Age of Seema= 10+ Age of Rekha.

➡Then,

=> X = 10+Y.

=> X-Y = 10 ...................(1)

And,

➡Ratio of there ages ,

=> X:Y = 5:3

=> X/Y = 5/3

=> 3X - 5Y = 0 .................(2)

➡Then, Multiply by 3 in (1),

♠ 3X -3Y = 30 ..............(3)

♠ 3X -5Y = 0..................(4)

[ Subtract its (3)-(4) ]

=> 2Y = 30

=> Y = 15.

➡Keep Y =15 in (1),

=>X -15 = 10

=>X = 25.

➡Thus:-

♠ Age Of Seema (X) = 25.

♠ Age Of Rekha (y) = 15.

➡Explanations

↪Seema is 10 year elder than Rekha .

=> X = 10+Y

=> 25 = 10+15

=>25 = 25
