Answer 1

Answer :

Given

• Sarita's present age is to be taken as X.
• Sarita's grafather's age is 5times her age .

To find

• (a) Sarita's age 5 years from now.
• (b) Her age 5 years before.
• (c) Her grandfather's age .

Solution

According to Question

Let the,

$\longrightarrow \:\textsf{ Sarita's present age be = X}$

So,

$\underline{\underline{\mathsf{(a)First\: part\: of \: Question \implies}}}$

$\mathsf{\longrightarrow \: Her \: age \: 5yrs \: from \: now \: Would \: be}$

$\mathsf{\longrightarrow \: Her \: present \: age\: -\: 5 years }$

$\mathsf{\longrightarrow \: x + 5 years }$

Therefore we have,

$\mathsf{\longrightarrow \: (a) \:Her \: age \: 5yrs \: from \: now = \boxed{x + 5}}$

$\rule{300}{1}$

$\underline{\underline{\mathsf{(b) Second\: part\: of \: Question \implies}}}$

$\mathsf{\longrightarrow \: Her \: age \: 5yrs \: ago \: Would \: be}$

$\mathsf{\longrightarrow \: Her \: present \: age \: - \: 5 years }$

$\mathsf{\longrightarrow \: x - 5 years }$

Therefore we have,

$\mathsf{\longrightarrow \: (b) \:Her \: age \: 5yrs \: ago = \boxed{x - 5}}$

$\rule{300}{1}$

$\underline{\underline{\mathsf{(c) Third\: part\: of \: Question \implies}}}$

$\mathsf{\longrightarrow \: Now \: it's \: given \: that Grandfather's \: age = 5 times \:her \: age }$

Therefore we have

$\mathsf{\longrightarrow \: Grandfather's \: age = 5 \times \: x }$

$\mathsf{\longrightarrow \: 5x}$

Therefore we have,

$\mathsf{\longrightarrow \: (c) \: Grandfather's \: age = \boxed{5x}}$

$\rule{300}{1}$

$\underline{\underline{\mathsf{\star \: \blue{Tips \: To \: Answer}}}}$

$\mathsf{If \: we \: need \: to \: find \: absolute\: value \: for above \: question}$

Then

$\rightarrow \mathsf{There \: would \: be \: some \: values \: given \: in \: question}$

$\rightarrow \mathsf{We\: just need\: to \: put \: those \: values \: and \: form \: some \: useful \: Equations}$

$\mathsf{And\: solve \: those \: equation \: to \: required\: answers }$

$\rule{300}{1}$

Answer 2

Solution :

1). what will be her age 5 years from now?

Let her present age be X.

Age 5 years from now = ( X + 5 ) years

2). what was the age 5 years back?

Age 5 years back = ( X - 3 ) years

3). Sarita's grandfather is 5 times her age what is the age of grandfather?

Age of Sarita = X

Age of grandfather = 6 × sarita's age

Age of grandfather = 6 × X

Age of grandfather = 6X.
