Statement I: Ali is one year younger to Geet. Sum of age of Ali and Chals is 20 years.

Statement II: Sum of ages of Dyna and Ena is 17 years.

Statement III: Sum of ages of Bela and Dyna is 32 years.

Which of the above statement is redundant to find the answer of the given question?

1. Both Statement I and III
2. Both Statement II and III
3. Statement I
4. Statement II
5. Statement III

Answer 1

Correct Answer - Option 1 : Both Statement I and III

Ali = 3 + Bela

Bela = 5 + Chales

Ali = Bela + Chales

(Dyna + 2) : (Ena + 2) = 3 : 4

Dyna = (3 Ena – 2)/4

Dyna + Ena + Fany + Geet = 50

7 Ena + 4 Fany + 4 Geet = 202

Statement I :

Geet = Ali + 1

Ali + Chals = 20

Ali + ali – 8 = 20

Ali = 14 years

Geet = 14 + 1 = 15 years

7Ena + 4Fanny + 4Geet = 202

7Ena + 4Fanny + 4 × 15 = 202

7Ena + 4Fanny = 124

Age of Fanny is not given.

Hence, this statement is redundant to find the answer.

Statement II :

Dyna + Ena = 17

Dyna = 17 – Ena

Dyna = (3Ena – 2)/4

Ena = 10 years

Statement III :

Bela + Dyna = 32

Dyna = 32 – Bela

Dyna = (3Ena – 2)/4

(3Ena – 2)/4 = 32 – Bela

Age of Bela is not given.

Hence, this statement is redundant to find the answer.
