Correct answer: (B) 6
If the couple married t years ago, present combined age = 56+2t (since average at marriage was 28 each) and daughter's age = t-2. Average of all three = 24 gives 56+2t+(t-2)=72, so t=6.

सही उत्तर: (B) 6
यदि दंपत्ति की शादी t वर्ष पहले हुई, तो वर्तमान संयुक्त आयु = 56+2t (चूंकि विवाह के समय प्रत्येक की औसत आयु 28 थी) और बेटी की आयु = t−2। तीनों की औसत आयु 24 से 56+2t+(t−2)=72, अतः t=6।
