Question

a man got 10% increase in salary if new salary is 154000 find is original salary

Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

[] Let the original salary of the man be 'x'.



[] Then, increment in his salary,

= 10% of total

= 10% of x

= 10/100 × x

= 10x/100

= x/10



[] Now, increased salary,

= original salary + Increment

= x + x/10

= (10x + x)/10

= 11x/10



[] But, according to the question, his new salary = 154000.

=> 11x/10 = 154000

=> x = 154000 × 10/11

=> x = 1540000/11

=> x = 140000

•°• His old salary = x = 140000

$\boxed{\boxed{\boxed{\bold{\green{Solution : \longrightarrow}}}}}$

$\bold{Let \: \:his \: \: orginal \: \: salary \: \: be \: \: Rs \: x.}$

$\bold{According \: \: to \: \: question}$

$\bold{x + 10\% \: \: of \: \: x = 154000} \\ \\ \bold{= > x + \frac{10}{100} \times x = 154000}$

$\bold{ = > x + \frac{x}{10} = 154000} \\ \\ \bold{= > \frac{10x + x}{10} = 154000} \\ \\ \bold{= > 11x = 154000 \times 10} \\ \\ \bold{= > x = \frac{154000 \times 10}{11}} \\ \\ \bold{= > x = 140000}$

$\bold\blue{\underline{Hence, \: \: his \: \: original \: \: salary \: \: is}} \\ \bold\blue{\underline{Rs \: \: 140000.}}$
