Answer 1

Question:

John's age is double that of rambo, and rambo's age is triple of mark. sum of the ages of john, mark and rambo is 140. what are their ages?

To find:

The ages of John ,Rambo and Mark...

Given:

$\text{let the age of Mark be x.}$

$\text{So, the age of Rambo will be 3x.}$

$\text{And, the age of john will be 6x.}$

Given:

Sum of there ages is 140.

According to the Question:

$6x + 3x + x = 140$

Solution:

$6x + 3x + x = 140$

$10x = 140$

$x = 14$

Age of Mark :

$x = 14years$

Age of Rambo:

$3x = 3(14years)$

$x = 42years$

Age of John:

$6x = 6(14years)$

$x = 84 years$

Answer 2

$\sf{\huge{\purple{\mathfrak{\underline{\underline{Question}}}}}}$

• john's age is double that of rambo, and rambo's age is triple of mark. sum of the ages of john, mark and rambo is 140. what are their ages?

$\sf{\huge{\purple{\mathfrak{\underline{\underline{Solution}}}}}}$

let the mark age be x

rambo's age = 3 x mark's age

rambo's age = 3 x X

rambo's age = 3x

john's age = 2 x rambo's age

john's age = 2 x 3X

john's age = 6x

ATQ:-

john's age + rambo's age + mark's age = 140

x + 3x + 6x = 140

10x = 140

x = 140/10

x = 14

mark's age = 14years

Rambo's age = 3x = 3 * 14 = 42years

John's age = 6x = 6 * 14 = 84years
