Question

4. Raju's salary increases by 12% every year. If his present salary is Rs. 4200, then his next year salary will be

​

Answer 1

Present salary = rs 4200

increase percent =12%

METHOD 1:

Increase %= 12%

Therefore,

increase in salary = 12 % of 4200

$= \frac{12}{100} \times4200$

$= 12 \times 42$

$= 504$

therefore, salary = 4200+504

= rs 4705

METHOD 2:

increase = 12%

therefore,

appreciation formula =

$p( 1 + \frac{r}{100} )$

$4200(1 + \frac{12}{100} ) \\ 4200 \times \frac{112}{100} \\ 42 \times 112 \\ \: rs. 4704$
