A.

4

B.

5

C.

6

D.

7

Answer with explanation

Answer: Option DExplanation

S+R+D+T = 78 – (i)

S = R + 4 – (ii)

D = T + 2 – (iii)

S = 7T – (iv)

7T = R+4

R= 7T – 4

h+w+d+s = 78 – (i)

7T+7T-4+T+2+T = 78

16T = 80

T = 5

d = T+2 = 5+2 = 7

The difference between the mother and her daughter is 30 years. 4 years hence, the age of mother will be four times that of her daughter. What is the age of the mother?

A.

36 years

B.

32 years

C.

42 years

D.

28 years

Answer with explanation

Answer: Option AExplanation

X – mother; y-daughter

x – y = 30

y = x – 30

After 4 Years

x + 4 = 4 (y + 4)

x + 4 = 4 (x – 30 + 4)

x + 4 = 4x – 120 + 16

4 + 104 = 4x – x

3x = 108

X = 36 years
