Question

Difference between 50% and 40% of a number is 2700 .What is the number

Answer 1

Answer:

27000

Hello

I hope this helps you!

Step-by-step explanation:

Let x be the number.

50% of x = 0.5x

40% of x = 0.4x

The difference between these is 2700

=> 0.5x - 0.4x = 2700

=> 0.1x = 2700

=> x = 2700 / 0.1 = 27000

Alternatively, just say the difference between 50% and 40% of x is 10% of x.

So...

10% of x is 2700

=> 0.1x = 2700

=> x = 2700 / 0.1 = 27000

Answer 2

Here's your answer

Let no be x

50/100*x-40/100*x=2700

1/2x-2/5x=2700

5x-4x/10=2700

X=27000
