​

Answer 1

Answer

The present age of Seema is 70 years

$\bf\large\underline{Given}$

• The present age of Seema is twice the age of Reena .
• Reena will be 40 years after 5 years .

$\bf\large\underline{To \: Find}$

• The present age of Seema

$\bf\large\underline{Solution}$

Let us consider the present age of Seema be x years and that of Reena be y years

$\sf \underline{\underline{According \: to \: the \: question}}$

$\sf\implies x = 2y \longrightarrow (1)$

$\sf \underline{ \underline{Again \: by \: question}}$

$\sf\implies y + 5 = 40 \\\\ \sf\implies y = 35$

$\sf\underline{\underline{Putting \: the \: value \: of \: x \: from \: (1)}}$

$\sf\implies x = 2\times 35 \\\\ \sf\implies x = 70$

Therefore, the present age of Seema is 70 years

Answer 2

$\tt\large\red{\underline{ Question : }}$

If the present age Seema is twice of Reena's age . Reena will 40 after 5 years. What is the Present age of Seema.

$\tt\large\red{\underline{ Answer : }}$

ɢɪᴠᴇɴ ᴛʜᴀᴛ,

1. Present age of Seema is twice of Reena's age.
2. Reena will be 40 years after 5 years.

ᴛᴏ ғɪɴᴅ,

• Present age of Seema.

ʟᴇᴛ,

1. Present age of Seema = a years.
2. Present age of Reema = b years.

ғʀᴏᴍ ᴛʜᴇ ǫᴜᴇsᴛɪᴏɴ,

◼ Seema age was twice of Reema age. So,

$\sf\:\implies a = 2b ..... (1)$

◼ Reena will be 40 years after 5 years.

$\sf\:\implies b + 5 = 40$

$\sf\:\implies b = 40 - 5$

$\sf\:\implies b = 35$

$\underline{\boxed{\bf{\blue{\therefore Present\:age\:of\:Reema\: = 35 years. }}}}$

• Put the value of b in (1)

$\sf\:\implies a =2(35)$

$\sf\:\implies a = 70$

$\underline{\boxed{\bf{\orange{\therefore Present\:age\:of\:Seema\: = 70 years. }}}}$
