Question

If one-fourth of the sum of number and 7 is 4 less than 3 times three number ,find the number

Answer 1

would let #1 = x. Then #2 = x+1 #3 = x+2 #4 = x+3 The problem says we want the sum of the first three. That will be x + (x + 1) + (x + 2) and that should be 60 more than the fourth. The fourth is x + 3; therefore, set them equal and add 60 to the fourth.

Answer 2

Given :

one-fourth of the sum of number and 7 is 4 less than 3 times three number

To Find:

find the number

Solution:

Let the number be x

One fourth of sum of number and 7 = $\frac{1}{4}(x+7)$

We are given that one-fourth of the sum of number and 7 is 4 less than 3 times the number

$\Rightarrow 3x-\frac{1}{4}(x+7)=4\\\Rightarrow 12x-(x+7)=16\\\Rightarrow 12x-x-7=16\\\Rightarrow 11x=16+7\\\Rightarrow 11x=23\\\Rightarrow x=\frac{23}{11}$

Hence The number is 23/11
