Question

If 7 is added to four-seventh of k to get 43, then what is the value of k?

Answer 1

Answer:

according yo given data

4k/7+7=43.

4k/7=36.

k=36*7/4.

k=63

Answer 2

The value of k = 63

Given :

7 is added to four-seventh of k to get 43

To find :

The value of k

Solution :

Step 1 of 2 :

Form the equation to find the value of k

Here it is given that 7 is added to four-seventh of k to get 43

So by the given condition

$\displaystyle \sf \bigg( \frac{4}{7} \times k \bigg) + 7 = 43$

Step 2 of 2 :

Find the value of k

$\displaystyle \sf \bigg( \frac{4}{7} \times k \bigg) + 7 = 43$

$\displaystyle \sf{ \implies } \frac{4k}{7} + 7 = 43$

$\displaystyle \sf{ \implies } \frac{4k}{7} = 43 - 7$

$\displaystyle \sf{ \implies } \frac{4k}{7} = 36$

$\displaystyle \sf{ \implies }k = 36 \times \frac{7}{4}$

$\displaystyle \sf{ \implies }k = 63$

Hence the required value of k = 63
