Question

If 10% of a number is 30 and 75% of the same number is 225, find 85% of that number.

Answer 1

Step-by-step explanation:

10%+75% = 85%

so, 85% of that number is (30+225) = 255

Answer 2

Answer:

255

Step-by-step explanation:

you should do the question in reverse like for the 10% of that number is 30,multiply 30 by 100 then divide it by 10.You will be able to find out the value of the whole number.

here:

30X100=3000

3000 divided by 10= 300.

225X100=22500

22500 divided by 75= 300.

Since we now know that the value of that number is 300, you can now go ahead and solev the problem.

300X85=25500

25500 divided by 100=255.
