Indian Overseas Bank LBO Mock 04 – Question 42

Question:

The ratio of present age of A and B is 3 : 4 respectively. The age of B eight years hence will be 5/3rd of the present age of A. If C is four years older than A, then find the difference between present age of B and C (in years)?

(a) 6

(b) 16

(c) 8

(d) 4

(e) 18

A और B की वर्तमान आयु का अनुपात क्रमशः 3 : 4 है। आज से आठ वर्ष बाद B की आयु A की वर्तमान आयु का 5/3 होगी। यदि C, A से चार वर्ष बड़ा है, तो B और C की वर्तमान आयु का अंतर (वर्षों में) ज्ञात कीजिए?

(a) 6

(b) 16

(c) 8

(d) 4

(e) 18

Correct Answer: (d)

Explanation:

Let A = 3x, B = 4x.
4x + 8 = (5/3) × 3x = 5x => x = 8.
A = 24, B = 32.
C = 24 + 4 = 28.
Difference B – C = 32 – 28 = 4 years.

माना A = 3x, B = 4x.
4x + 8 = (5/3) × 3x = 5x => x = 8.
A = 24, B = 32.
C = 24 + 4 = 28.
B और C का अंतर = 32 – 28 = 4 वर्ष।
