Question

the ratio of age of raj and ram is 8:7.if the age of ram be 21 years,find the age of raj?​

Answer 1

Answer:

24 years

Step-by-step explanation:

let the age of Raj be x years

ratio of age of raj and ram = 8:7

age of ram = 21 years

age of raj/age of ram = 8/7

so, age of raj/21 = 8/7

that is, age of raj = 8×21/7 = 8×3 =24 years

hence,the age of raj is 24 years

Answer 2

Given

• Ratio of age of Raj and Ram is 8:7.
• Age of Ram is 21 years.

⠀

To find

• The age of Raj.

⠀

Solution

• Let the ratio of ages be x.

⠀

Then,

$\tt\longmapsto{}$ Age of Raj = 8x

$\tt\longmapsto{}$ Age of Ram = 7x

⠀

★ It is given in the question that age of Ram is 21 years.

⠀

Therefore,

$\tt\longrightarrow{7x = 21}$

⠀

$\tt\longrightarrow{x = \cancel{\dfrac{21}{7}}}$

⠀

$\bf\longrightarrow{x = 3}$

⠀

By putting the value of x, we will find the age of Raj.

$\tt:\implies{Age\: of\: Raj = 8 \times 3}$

$\tt:\implies{Age\: of\: Raj = 24\: years}$

⠀

Hence,

• Age of Raj is 24 years.
