Question
If m = 3, how much greater is 10m than 6m ?
- 3
- 4
- 12
- 30
The correct answer is: 12
HINT: Solve using the value of m = 3.
Complete step by step solution:
Given m = 3.
To find, how much greater is 10m than 6m.
Let 10m…(i) and 6m…(ii)
Substitute the value of m = 3 in (i) and (ii).
We get (i) to be 10m =10 × 3 = 30…(iii)
And we get (ii) to be 6m = 6 × 3 = 18…(iv)
On subtracting (iv) from (iii), we get 30 - 18 = 12
So 10m is greater than 6m by 12.
Hence option C is the correct answer.
