Question 4 Explanation:

Let present age of Mother is M and present age of daughter is D.

M/D = 5/1And,

(M+5)/(D+5) = 3/1Solve for M and D,

M+5 = 3D+15 5D+5 = 3D+15 2D=10We get,

D=5 and M=25Further after 10 years daughter age will be

= 5+5+10 = 20 yearsAnd, mother age will be = 25+5+10 = 40 yearsHence, mother's age would be 40/20=2 times higher than that age of her daughter. Option (B) is correct.

Question 6 Explanation:

Let a = 1/y and b = 1/z. The average of a, b is,

= (a+b)/2 = (1/y+1/z)/2 = (y+z)/(2yz)The Harmonic mean x is the reciprocal of this average so,

x = (2yz)/(y+z)Given,

y = 30, z = 45Therefore,

x = (2yz)/(y+z) = (2×30×45)/(30+45) = 36Option (D) is correct.
