Question

Vihan's salary increase by 10% on promotion . Find his previous salary if his new salary is ₹77000​

Answer 1

Answer:

His previous salary is Rs. 70000.

Step-by-step explanation:

$Let \ the \ previous \ salary \ be \ 'x'.$

$\frac{100+10}{100} * x = 77000$

$\frac{110}{100} * x = 77000$

$1.1x = 77000$

$x = \frac{77000}{1.1}$

$x = 70000$

$Hence, his \ previous \ salary \ is \ Rs. 70000.$
