Question

a mans salary over a period of ten year increased by 80%. If it was £1350 at the end of ten years, what was it at the beginning?​

Answer 1

Answer:

Man's salary after 10 years = 1350

Let initial salary be 'x'

We see that x has increased by 80% over a span of 10 years

so,

x + 80x/100 = 1350

after solving for x, we see that the initial salary is 750
