Question

What single decimal multiplier would you use to increase by 5% followed by a 20% increase?

Answer 1

Answer:

1.26 is the single decimal multiplier.

Step-by-step explanation:

Let a number be x.

If x is increased by 5% then the value of the number is( (100+5) /100) ×x=1.05x

Again if 1.05x is increased by 20% then the value of the number=((100+20) /100) ×1.05x = 1.2×1.05x=1.26x

Thus it is found that single decimal multiplier used for successive increase of 5% and 20% is 1.26

Answer 2

The single decimal multiplier is 26%.

Step-by-step explanation:

Since we have given that

You use to increase by 5% followed by 20% increase.

So, the single decimal multiplier would be

$x+y+\dfrac{xy}{100}\\\\=5+20+\dfrac{20\times 5}{100}\\\\=25+1\\\\=26\%$

Hence, the single decimal multiplier is 26%.
