How do i work this out?

Answer 1

She has 45% of the original amount left

Ratio and proportions

Fractions are written as a ratio of two integers

Given the following

Initial amount. = ∈4000

Amount given to her sister = 1/4 * 4000 = 1000

Amount given to her brother = 40% of 3000 = 1200

Amount left = 4000 - (1000+1200)

Amount left = ∈1800

Determine the percentage left

x * 4000 = 1800

x = 1800/4000

x = 0.45

x = 45%

Hence she has 45% of the original amount left
