ᴀ ᴍᴀɴ sᴘᴇɴᴅs 87% ᴏғ ʜɪs sᴀʟᴀʀʏ. ɪғ ʜᴇ sᴀᴠᴇs

ʀs. 325; ғɪɴᴅ ʜɪs sᴀʟᴀʀʏ.

$\huge\mathtt\red{Answer}$

$\underline\mathtt{Solution}$

$\bf\ Expenditure = {\dfrac{87}{100}} \: of \: x$

$\bf\ = Rs. {\dfrac{87x}{100}}$

$\bf{Saving =Rs.325}$

$\bf\ X - {\dfrac{87x}{100}} = 325$

$\bf\dfrac{100 x \: \: 87x-}{100} { \: = 325}$

$⇝\bf\dfrac{13x }{100} = 325$

$\bf \: x = \dfrac{325 × 100}{13}$

$⇝\bf \: x = \dfrac{32500}{13}$

$\bf\fbox\green{X = 2500}$

Answer 2

Answer:

ɪғ ᴛʜᴇ ᴍᴇɴ sᴘᴇɴᴅs 87% ᴏғ ᴛʜᴇ sᴀʟᴀʀʏ, ᴛʜɪs ᴍᴇᴀɴs ʜᴇ sᴀᴠᴇs 100−87=13% ᴏғ ᴛʜᴇ sᴀʟᴀʀʏ.

ʙᴜᴛ ɢɪᴠᴇɴ, ʜᴇ sᴀᴠᴇs ʀs.

sᴏ,

⇒ 13%×sᴀʟᴀʀʏ=325

⇒

$\frac{13}{100} \times salary = 325$

$∴ Salary=325× \frac{100}{13} = Rs.2500$
