Answer 2

Given data : The salary of a clerk was increased by 7%.

If his present salary is 1519.40 units.

To find : What is the salary before the increament.

Solution : Let, before the increment the salary be x.

Hence, salary increased by 7 % of x.

➜ salary increase by = 7x/100

Hence,

• present salary of clerk = x + (7x/100) ----{1}

Here, a/c to given;

➜ present salary of clerk = 1519.40 ----{2}

Now, from {1} and {2}

➜ 1519.40 = x + (7x/100)

➜ 1519.40 = (100x + 7x)/100

➜ 1519.40 = 107x/100

➜ 107x = 1519.40 * 100

➜ 107x = 151940

➜ x = 151940/107

➜ x = 1420 units.

Answer : Hence, the salary before increment is 1420 units.

{More info :

➜ increment = present salary of clerk - x

➜ increment = 1519.40 - 1420

➜ increment = 99.4 units}

{Verification :

➜ Present salary of clerk = x + (7x/100)

put value of x in above equation.

➜ Present salary of clerk = 1420 + (7 * 1420/100)

➜ Present salary of clerk = 1420 + (9940/100)

➜ Present salary of clerk = 1420 + 99.4

➜ Present salary of clerk = 1519.4

Hence it verified.}
