Quantitative Aptitude (SBI-CL) Data Sufficiency

What will be the height of three friends Rahul, Robert and Priyanka altogether, if Priyanka’s height is 39 cm?

Statement I : The sum of the heights of Rahul and Priyanka is equal to 160 cm.

Statement II : The height of Robert is equal to 3 times the height of Priyanka

If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question

If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question

If the data either in statement I alone or in statement II alone is sufficient to answer the question

If the data in both statements I and II together are necessary to answer the question

If the data given in both statements I and II together are not sufficient to answer the question.

Explanation:

From statement I :
Rahul + Priyanka = 160 cm .......... (i)
From statement II :
Robert = 39 × 3 = 117 cm ..............(ii)
Adding equations (i) and (ii)
Rahul + Priyanka + Robert = 160 + 117 = 277 cm
∴ Both statements are required to answer the question.
Hence, option D is correct.
