Correct Answer: 16 years
Explanation:
Let their ages one years ago be 4x and 3x years.
? (4x + 2)/(3x + 2) = 5 / 4
? 4(4x + 2) = 5(3x + 2)
? x = 2
? Sum of their present ages = (4x + 1) + (3x + 1) = 16 years
Correct Answer: 24 years
Explanation:
Sum of age of A and B, 3 years ago = (18 x 2) = 36 years
Sum of ages of A, B and C, now = (22 x 3) = 66 years
Sum of ages of A and B, now = (36 + 6) years = 42 years
? C's present age = (66 - 42) years = 24 years
Correct Answer: 24 years
Explanation:
Let Anil's age = x years
Then, Prashant's age = (48 - x) years
Let the age of Jayesh be P years.
Then, P - (48 - x) = x - P
? 2p = 48
? p = 24
Correct Answer: 35 years
Explanation:
Let A's age 10 years ago = x years
Then, B's age 10 years ago = 2x years
? (x + 10) / (2x + 10) = 3 / 4
? 4(x + 10) = 3(2x + 10)
? x(6 - 4) = 40 - 30
? x = 5
&ther4; Total of their present ages = (x + 10) + (2x + 10)
= (3x + 20)
= 35 years
Correct Answer: 12 years, 44 years
Explanation:
Let the present ages of son and father be x years and (56 - x) years respectively.
Then, (56 - x + 4) = 3(x + 4)
? 4x = 48
? x = 12
So, their present ages are 12 years, 44 years respectively.
Correct Answer: 10 years
Explanation:
Let the ages of A and B be 2x and 3x years respectively.
From question, (2x + 5) / (3x + 5) = 3 / 4
? 4(2x + 5) = 3(3x + 5)
? x = 5
&ther4; A's present age = 2x = 10 years
Correct Answer: 5 years
Explanation:
Let the ages of father and son be 6x and x respectively.
From question, (6x + 5) / (x + 5) = 7 / 2
? 2(6x + 5) = 7(x + 5)
? (12 - 7) x = 35 - 10
? x = 5
? Son's present age = 5 years
Correct Answer: 11 : 3
Explanation:
Let son's age 1 year ago be x years.
? Father's age 1 year ago = 4x years
? 4x + 7 = 2(x + 7) + 9
? 2x = 23 - 7
? x = 8
Ratio of father's and son's present ages = (4x + 1) : (x + 1) = 33 : 9 = 11 : 3
Correct Answer: 7 : 3
Explanation:
Let son's age 10 years ago be x years.
? father's age 10 years ago = 3x years
? 3x + 20 = 2(x + 20)
? x = 20
? Ratio of their present ages = (3x + 10) : (x + 10) = 70 : 30 = 7 : 3
Correct Answer: 1 : 3
Explanation:
Let the ages of Laxmi and her mother be 11x and 3x respectively.
From question, 11x - 3x = 24
? x = 3
? Ratio of their ages after 3 years = ( 3x + 3) : (11x + 3 )
= 12: 36 = 1 : 3
