- Question
Each question contains Quantity I and Quantity II. Read the contents clearly and answer your questions accordingly. Quantity I: 3 years ago the ratio of age of A and B is 3: 4 after 2 years the sum of their ages is 45. Then find the present age of A? Quantity II: 5 years ago, the ratio of age of p and Q id 3: 4 P?s age after 6 years is equal to the present age of Q. the find the present age of P?
Options- A. Quantity I > Quantity II
- B. Quantity I ? Quantity II
- C. Quantity I < Quantity II
- D. Quantity I < Quantity II
- Correct Answer
- Quantity I < Quantity II
ExplanationQuantity I= Let 3 year ago the age of A and B be 3x and 4x respectively
Then ATQ 3x+5+4x+5=45 X=5
Hence present age of A=3x+3=18year
Quantity II== Let 5 year ago the age of p and q be 3x and 4x respectively
Then ATQ
3x+11=4x+5
X=6 Hence present age of P=3x+5=23
Hence Quantity I < Quantity II

James age = 2/7 x
James brother age = 2x/7 + 3
x = 42
=> 2x/7 = 12 yrs
Correct Answer: 9, 12
Correct Answer: 53
Correct Answer: 55 yrs
Correct Answer: 9
Explanation:
Let the present ages of A & B to be ?a? & ?b? respectively.
Hence, 2 years ago, their ages must have been (a-2) & (b-2) respectively.
Average of their ages at that time = 26
Hence,
[(a-2)+(b-2)]/2 = 26
(a-2)+(b-2) = 52
a+b = 56
Age of A, 5 year hence = 40 years
Hence, (a+5) = 40
a = 35 years
Hence, b = 56 - 35 = 21 years
B = (C-5)
Hence, C = 21+5 = 26 years
Age difference between A & C = 35 - 26 = 9 years.
Correct Answer: 13
Explanation:
Ans.
Currently :
A+B+C+D = 76
According to ques , after 7 years
A+B+C+D = 7x+6x+5x+8x = 76+7*4
26x = 76 + 28
X = 104/26
x = 4
C?s present age = 5x ? 7 =20 ? 7
= 13
Correct Answer: 62 Years
Explanation:
Let the average of 8 men be x. Age of new man be N.
Total age of 8 men = 8x
? x + 4 = ((8x ? 30) + N)/8
? 8x + 32 = 8x ? 30 + N
? N = 32 + 30
? N = 62
Correct Answer: 8
