b) what percent of 2kg is 25g

a)  Reena salary is $ 1500

b) 1.25 % of 2 kg is 25g

Solution:

Given that,

a) Reena saves rs 300 from her salary

This is 20% of her salary

Let "x" be the original salary

Then, we can say,

20 % of x = 300

Solve for x

Thus her salary is $ 1500

b) what percent of 2kg is 25g

We know that,

1 kg = 1000 g

2 kg = 2000 g

Let "x" be the required percent

Then, we can say,

x % of 2000 g is 25 g

Therefore,

Thus 1.25 % of 2 kg is 25g
