Answer 2

Correct Question:

If a number is decreased by 8 it equal to 20. Find the number.

Answer :-

• The required number is 28.

Step-by-step explanation:

To Find :-

• The number

Solution:

Given that,

• A number is decreased by 8, it which is equal to 20

Assumption: Let us assume the required number as "n"

Therefore,

• n - 8 = 20

=> n - 8 = 20

Transposing -8 to R.H.S from L.H.S,

=> n = 20 + 8

=> n = 28

Hence, The required number is 8.

Now, Verification

• n - 8 = 20

We have,

• L.H.S = n - 8
• R.H.S = 20

By putting the value of n in L.H.S, We got [n = 28]

=> n - 8

=> 28 - 8

=> 20

Now,

• L.H.S = 20
• R.H.S = 20

So, L.H.S = R.H.S

Hence, Verified!
