Ali is 3 years older than Bela who is 5 years older than Chals. The ratio of age of Dyna and Ena after two years will be 3 : 4 years. Sum of ages of Dyna, Ena, Fanny and Geet is 50 years. What is the present age of Ena? 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?
Ali is 3 years older than Bela who is 5 years older than Chals. The ratio of age of Dyna and Ena after two years will be 3 : 4 years. Sum of ages of Dyna, Ena, Fanny and Geet is 50 years. What is the present age of Ena? 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? Correct Answer 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.
