Question

Tim's pay increased by 5% to £880
a fortnight.
What was his pay before the
increase?

Answer 1

Answer:

• £838.10

Step-by-step explanation:

Let the previous salary be x

Increase = 5%

New salary = £880

• x + 5% = 880
• x*1.05 = 880
• x = 880/1.05
• x = £838.10 (rounded)

Answer 2

Answer:

£838.10

Step-by-step explanation:

let x be past pay

according to the question

$x \times \frac{105}{100} = 880$

$x = 880 \times \frac{100}{105}$

$x = 838.10$
