ANS:B -
16 years
Explanation:
Manick's present age = 12 years, Rahul's present age = 4 years.Let Manick be twice as old as Rahul after x years from now.Then, 12 + x = 2 (4 + x) 12 + x = 8 + 2x x = 4.Hence, Manick's required age = 12 + x = 16 years.

ANS:D -
120 rolls
Explanation:
Number of cuts made to cut a roll into 10 pieces = 9.
Therefore Required number of rolls = (45 x 24)/9 = 120.

ANS:C - 30
Explanation:
Let the number of boys and girls participating in sports be 3x and 2x respectively.Then, 3x = 15 or x = 5.So, number of girls participating in sports = 2x = 10.Number of students not participating in sports = 60 - (15 + 10) = 35.Let number of boys not participating in sports be y.Then, number of girls not participating in sports = (35 -y).Therefore (35 - y) = y + 5 2y 30 y = 15.So, number of girls not participating in sports = (35 - 15) = 20.Hence, total number of girls in the class = (10 + 20) = 30.

ANS:D - 60
Explanation:
Let x and y be the number of deer and peacocks in the zoo respectively. Then,
x + y = 80 ...(i) and
4x + 2y = 200 or 2x + y = 100 ...(ii)
Solving (i) and (ii), we get) x = 20, y = 60.

|
ANS:D - 24
Explanation:
Total number of routes from Bristol to Carlisle = (4 x 3 x 2) = 24.
|
ANS:C -
£ 13
Let money with Ken = x. Then, money with Mac = x + £ 3.Now, 3x = (x + x + £ 3) + £ 2 x = £ 5.Therefore Total money with Mac and Ken = 2x + £ 3 = £ 13.
|
ANS:B - 12
Explanation:
Let the number of boys be x. Then, (3/4)x = 18 or x = 18 x(4/3) = 24.
If total number of students is y, then (2/3) y = 24 or y = 24 x (3/2) = 36.
Therefore Number of girls in the class = (36 - 24) = 12.
|
ANS:B - 15
Let son's age be x years. Then, father's age = (3x) years.Five years ago, father's age = (3x - 5) years and son's age = (x - 5) years.So, 3x - 5 = 4 (x - 5) 3x - 5 = 4x - 20 x = 15.
