In the percentage terms,
100 = 66 59 – X
X = 125 – 100 = 25

Now,

Answer: A

Solution: 

(0.00001225/ 0.00005329) ^1/2
= (1225/5329) ^1/2 , Just eliminate the decimal points.
= 35/73

Answer: B

Solution: 

Given that,
x (1/y) = 1
or, x = 1- (1/y)
or, x = (y-1)/y
1/x = y/(y-1)

Again,
y (1/z) = 1
or, 1/z = 1-y
or, z = 1/(1-y)

Now,
z 1/x = 1/(1-y) y/(y-1) = (y-1)/(y-1) =1

Answer: C

Solution: 

Let the age of mother = X
