3.Answer: B
Total age of whole family = 30×5 =150
Total age of mother and father = 25×2 = 50
Ratio of father and mother = 3: 2
Father = 30 Mother = 20
Total of grandparents age is = 40×2 =80
Son = [150 – (50 + 80)] = 20

5.Answer: D
120 m ————- 4 days
240 m ————-?
(240 * 4) / 120 = 8 days
6.Answer: A
Let x=4m, y=3m
X+y = 7
(x+y)2 = 72
X2 + y2 + 2(12) = 49
X2 + y2 = 49 – 24 = 25
(4m)2 + (3m)2 = 25 => m2 = 1
X = 4, y = 3
7.Answer: C
Total marks = 100×2 = 200
Let x be the no. of questions answered correctly and y be the no. of questions answered wrong.
X+y=50—–à(1)
4x-y=100 —-à(2)
Solve (1) and (2)
X=30, y=20
8.Answer: C
Area of a cone = 1/ 3 πr2h = 231m2
1/3× 22/7× 7×7 × h = 231m
H = 4.5 m
9.Answer: C
10.Answer: B
