Indian Overseas Bank LBO Mock 02 – Question 56

Question:

The present ages of P and Q are in the ratio 4 : 5. Six years hence, the ratio of their ages will become 5 : 6. What is the present age of P?

(a) 20 years

(b) 24 years

(c) 28 years

(d) 30 years

(e) 18 years

P और Q की वर्तमान आयु का अनुपात 4 : 5 है। छह वर्ष बाद, उनकी आयु का अनुपात 5 : 6 हो जाएगा। P की वर्तमान आयु क्या है?

(a) 20 वर्ष

(b) 24 वर्ष

(c) 28 वर्ष

(d) 30 वर्ष

(e) 18 वर्ष

Correct Answer: (b)

Explanation:

Let present ages be 4x and 5x.
After 6 years: (4x + 6) / (5x + 6) = 5 / 6.
6(4x + 6) = 5(5x + 6) => 24x + 36 = 25x + 30 => x = 6.
Present age of P = 4x = 4 * 6 = 24 years.

(4x + 6) / (5x + 6) = 5 / 6 => 24x + 36 = 25x + 30 => x = 6।
P की वर्तमान आयु = 4 * 6 = 24 वर्ष। सही उत्तर (b) is (b).
