Question

The salary of a bank clerk was increased by 10%. If the present is Rs. 8503

Answer 1

Answer:

Step-by-step explanation:

Suppose the salary of bank clerk was originally 100 % which accounts for x RS

SO , x RS = 100 %

Then he received an increase of 10 % which means he now earns 110 % of what he used to earn earlier , now here we are given that his new salary or the present salary is 8503 RS .

SO , 8503 RS = 110 %

Now we have 2 equations , x RS = 100 %

                                               8503 RS = 110 %

So we can use the method of cross multiplication to find x or the earlier salary .

∴ x = 100 × 8503 ÷ 110

∴ x = 10 × 773

∴ x = 7730 RS

So his earlier salary was 7730 RS .
