What is the value of x/3+y/3? (1) (x+y)/3 = 6 (2) x + y = 18

Question

What is the value of x/3 + y/3?

(1) (x + y)/3 = 6

(2) x + y = 18

blueviper · Answer

We can rewrite the equation as

ST (1) (x + y)/3 = 6 => x/3 + y/3 = 6... Sufficient

ST (2) x + y = 18 Dividing both sides by 3 => (x+y)/3 = 6 => x/3 + y/3 = 6... Sufficient

Answer is option D.

KSBGC · Answer

we are looking for the value of  \frac{x}{3} + \frac{y}{3.}

\frac{x}{3}  + \frac{y}{3}

= \frac{x + y}{3}

Statement 1: Sufficient. that's what we are looking for.

Statement 2: the value of x + y is given. So, 18/3 = 6. Sufficient.

The best answer is D.

Solution

To find:  
 • The value of the expression x/3 + y/3 = (x + y)/3

Analysing Statement 1  
As per the information given in statement 1, (x + y)/3 = 6
 • From this statement, we can directly say the value of the expression x/3 + y/3 is equal to 6.

Hence, statement 1 is sufficient to answer the question.

Analysing Statement 2  
As per the information given in statement 2, x + y = 18
 • Therefore, we can write x/3 + y/3 = (x + y)/3 = 18/3 = 6

Hence, statement 2 is sufficient to answer the question.

Combining Both Statements  
Since we got the answer from either of the statements independently, this step is not required.

Hence, the correct answer is option D.

Answer: D

Mandy001 · Answer

Option D

x/3 + y/3 = (x+y)/3

So we either need the value of (x+y) or (x+y)/3

Hence, both of the answers are individually sufficient.

value based DS question

#1
x+y= 18

so (x+y)/3 = 6
sufficient

#2
same info as 1 
sufficient
IMO D

AyushCrackVerbal · Answer

To Find

The value of x/3 + y/3  OR  the value of (x+y) / 3

Statement 1

(x+y)/ 6 = 3

x+y = 18

(x+y)/3 = 6

Since we have got one unique value of (x+y) /3, Statement 1 is independently sufficient.

Statement 2

x + y = 18

(x+y)/3 = 18/3 = 6

Since we have got one unique value of (x+y) /3, Statement 2 is independently sufficient.

Since both the statements are independently sufficient, the correct answer is  D

What is the value of x/3+y/3? (1) (x+y)/3 = 6 (2) x + y = 18
