Q1. Option B
Present ratio P:M ==>2:9
After 10years P:M=4:11
(2x+10)/(9x+10) = 4/11
Then Mother‘s present age=9*5=45yrs.
After 15 yrs Mother‘s age is=60yrs.
Q2. Option C
A = C – 18 —2
C + 9 = 47 =>C=47-9=38yrs.
A – B = C —3
From 2 A=38-18=20yrs.
From 1 20/B=5/x==> B=4x
From 3 4x-20=38
Q3. Option A
Let 16 yrs ago the age of mine was=x
My present age is 9.6+16=25.6
Present age of my Uncle =8*9.6+16=92.8
Required ratio =(25.6-8)/(92.8-8) =17.6/84.8=11:53.
Q4. Option D
According to 2nd condition
A‘s age =6*5=30.
Q5. Option C
The age of family after 6 years =36*5=180
The age of bride after 6 years=180-(126+18+5)
Age of bride at the time of marriage=31-6=25yrs.
Q6. Option B
From option 54-45=1/11(45+54)
Q7. Option D
M – L = L – N
(M + N) = 2L
Given (M + N) = 60
But can‘t able to find M value
Therefore, cannot be determined.
Q8. Option C
Let daughter‘s age = A and mother‘s age = B
Given: 3A+B = 75 and A+2B = 80
Solving A, we will get A = 14.
Q9. Option B
Let P‘s age = X
R 12 yrs older than P so R‘s age = x+12
Q is thrice as old as P so Q‘s age = 3x
x + (x+12) + 3x = 57
=> 5x = 45
x = 9
P‘s age = 9
Q‘s age = 3x = 27
R‘s age = x+12 = 21
Q10. Option A
Epsi age =7-2=5yrs
Let Sharmi age be x years.
Q11. Option B
Let Arun‘s present age be x years. Then, father‘s present age =(x + 3 x) years = 4x
Required ratio, (4x+16)/(x+16) =48/24=2.
Q12. Option A
Let the daughter‘s age be x years.
Then, father‘s age = 4x.
Mother‘s age = 4x – 10; Son‘s age = x + 6.
So, x + 6 = (4x-10)/2 ==> x=11.
Therefore Mother‘s age = 4X – 10= 44 – 10 = 34 years
Q13. Option C
Present age of Thomas‘s son = x years
Thomas‘s present age = 3x years
Thomas‘s father‘s present age = 3x*2=6x
X+3x+6x=33 1/3 *3
Then diff between Thomas son‘s and father‘s age is
Q14. Option D
Father‘s age was 28 years when my sister was born.
My sister‘s age was 4 years when my brother was born.
Therefore, father‘s age was 28+4=32 years when my brother was born.
Q15. Option D
Can‘t be determined
