Question

1. A number added to its two third value is equal to 35. What is the number?
(a)21
(b) 22
(c)35
(d) 20​

Answer 1

Answer:

Answer is option (a)$21$

Step-by-step explanation:

We can check it directly from the options. That is consider the first option

$21$, its two third is    $21*\frac{2}{3} =7*2=14$,  and $21+14=35$,

hence the answer.

If it wrong, then try with the next option, and keep going on.

Or otherwise,  let the number be $x$

then it is given that  

               $x+\frac{2}{3} x=35\\\\\frac{3x+2x}{3} =35\\\\\frac{5x}{3} =35\\\\5x=35*3=105\\\\x=105/5=21$

So we get $x=21$

Hence the answer

thank you

Answer 2

To find  : missing number .

Given : A number added to its two third value is equal to $35$ .

Solution :

• Let , missing number be $x$ .
• As per the given data we know that ,number added to its two third value is equal to $35$ .
• We write it as , $x + \frac{2}{3} x = 35$
• Further solving by leaving variable at LHS and transposing constants at RHS we find value of $x$ .

•  $x + \frac{2}{3} x = 35$  

       $\Rightarrow \frac{3x + 2x }{3} = 35 \\\Rightarrow \frac{5x}{3} = 35 \\\Rightarrow 5x = 105 \\\Rightarrow x = 21$

Hence, missing number is $21$ .
