half of a no is increased 10 by 12 what is the no please explain it
Answers
-In this question we are given that a number is first increased by 10% and then reduced by 10%. For this, let the number at the start be 100 and apply the directions given in question to get the result. Hence the number is decreased by 1%. Therefore, the correct is B.
Answer:
hense the number is 4 ,so the number x is 4.
Step-by-step explanation:
+10=12
You can start by getting rid of the denominator ‘2’.
(2)(x2+10)=(2)(12)
x+20=24
Now, it’s just a harmless little algebraic expression.
x=24−20
x=4
Let the number be X.
Half of number will be X/2
On increasing 10 we get, (X/2) +10———-(i)
Which is equal to 12.
Hence,
(X/2) + 10=12
(X/2)=12–10
X/2 = 2
X=2×2
X=4
Let the number be “x”
As per the given statement half of a number is increased by 10 is 12,
=> x/2+10 = 12
=> x/2 = 12–10=2
=> x=2*2 = 4
The number is 4
