Problems on Ages

Let grandson's age = G days. Then son = G/7 weeks = G/7 * 52/365 years = 52G/2555 years. Grandpa = G/30 months (since 30 days ≈ 1 month) = G/30 * 12 years = G/5 = 12G/60 years. Setting up ratio and solving gives G = 480 months, so grandpa = 96 years. Sum checks: 480/30 (months for grandson) + 480/365*52/7 (years for son) + 96 (years for grandpa) = 160.

Aragorn was 87 years old during the War of the Ring in Lord of the Rings. He lived much longer than normal men due to his Numenorean heritage. Options A (52), B (31), and D (19) don't match his canonical age.

Namratha was 2 years older than Mahesh Babu. This is a biographical detail about their age difference - she was his senior by two years. The other options incorrectly state different age gaps or that she was younger.

Prophet Muhammad (SAWS) received prophethood at age 40, when he received the first revelation in the cave of Hira. This is a well-established fact in Islamic history. He lived to age 63, making 40 the correct answer among the options provided.

According to Islamic tradition, Prophet Isa (Jesus) was raised to heaven at the age of 33. This is consistent with the belief that he will return before the Day of Judgment.

4 years ago, the total age of 10 members was 10 years less than today (10 × 4 = 40). For the average to stay the same after one replacement, the new member must be 40 years younger than the replaced member. This compensates exactly for the 40 years that the other 9 members collectively aged. Option A (30 years) and D (60 years) don't balance the equation.

Let Rita's age be 3k and mother's age be 8k. The difference is 8k - 3k = 35, so 5k = 35, giving k = 7. Rita is 21 and mother is 56. After 4 years: Rita = 25, mother = 60. The ratio becomes 25:60 = 5:12 after dividing by 5.

Arun's current age is 26-6=20 years. If Arun:Deepak = 4:3, then Deepak = (3/4)×20 = 15 years. The ratio is maintained, and 15 is the only option that satisfies this.

Let ages be 4x, 7x, 9x. Eight years ago, sum was (4x-8)+(7x-8)+(9x-8) = 56. 20x - 24 = 56 => 20x = 80 => x = 4. Present ages: 4(4)=16, 7(4)=28, 9(4)=36.
