Saraswathy  (10 years ago)

Both statements I nd II together are necessary to answer the question

A = 2C+3E
A = 30
2C+3E = 30
Substitute values for C nd E to get 30
C=1, C=2 ll not produce 30
C=3, E=8
2(3) + 3(8) = 30

Hence both are necessary

Ans : Both statements I nd II together are needed

Saraswathy  (10 years ago)

Sorry it might be "Both are not sufficient" bcozzz
2C+3E =30
There are many possible values of (C,E) ll yield 30... (3,8), (6,6)(9,4)(12,2)
Possible values of E ll be 8,6,4,2...
So we cant find the exact no. of engg graduates...

Hence "Both I nd II are not sufficient to answer the question"
