Answer with Explanation:
1). Answer :b)
Let the present age of A and B are 4x and 5x
According to the question,
(4x+4) / (5x+4) = 5/6
24x+ 24 = 25x + 20
x = 4
Hence, the present age of 5(4) = 20 years
2). Answer: a)
The present age of mother and daughter are 2x and x
Four years hence, their ages will be,
(2x+4)/(x+4) = 13 /7
14x+28 = 13x+52
x =24
∴ the present age of mother is 2(24) = 48
Hence, 5 years ago the age of mother was 48 – 5 = 43 years
3). Answer: d)
We cannot determine the age of oldest one in the family.
4). Answer: c)
The total age of 6 members = 38 × 6 = 228
Excluding the age of youngest one = 228 – 8 = 220
The average of the family at the time of youngest one birth = 220 /5
= 44
Â
5). Answer: b)
Let the present age of Nithya be, x
∴ the present age of Priya = x -8 and Divya = x – 2
According to the question,
(x-8) / (x-2) = 3/4
4x – 32 = 3x -6
x =26
Hence, the present age of Priya = 26 – 2 = 24 years
6). Answer: c)
The present age of A and B are, (15x+10) and (11x+10)
According to the question,
(15x + 10 +11)/ (11x+ 10 + 11) = 9/8
120x + 168 = 99x + 189
21 x = 21
∴ x =1
Hence, the present age of Bis 11 (1) + 10 = 21 years
7). Answer: a)
When Karthik was born, his mother’s age was 28 years and his brother is 4 yrs elder to Karthik.
∴ Karthik mother’s age (at his brother’s birth) = 28 – 4 = 24 years
Karthik father was 30 years old when his sister was born. Karthik’s sister is 5 years elder to his brother.
∴ The age of Karthik father (at his brother’s birth) = 30 + 5 = 35 years
Hence, the age of Karthik mother and father was 24yrs and 35yrs
8). Answer: d)
The average age, when the age of the mother is included is 10 × 2 = 20
∴ the total age = 4 × 20 = 80
Hence, the mother’s age = 80 – 30 = 50 years
9). Answer: a)
Present age of A and B are 6x and 5x
According to the question,
(6x +15) / (5x+15) = 9/8
48x + 120 = 45x +135
3x = 15
x = 5
Hence, the age of A 8 years ago was, 6 (5) – 8 = 30 – 8 = 22 years
10). Answer: b)
Let the age of Prabha 6 years ago be x,
The present age of Prabha is (6+x)
∴ (6+x) = 16/13 x
(16/13)x – x = 6
3/13 x = 6
∴ x = 26
∴ the present age of Prabha is 26+6 = 32
Hence, the age of Prabha’s son = 1/8 × 32 = 4 years
