आज की पोस्ट इसप्रकार है:

Q 2519) The present age of Anil is one third of his father’s age. After 15 years, he will be half old as his father. The present age of father is —

(A) 40 years    (B) 42 years   (C) 45 years   (D) 48 years

Ans: (C) 45 years

Solution:

Suppose the present age of father is x  years.

Therefore, the present age of son = 1/3x years

As per question after 15 years,

1/3x + 15 = 1/2 (x+15) = 1/2x +15/2 and 1/3x + 15 = 1/2x +15/2

1/3x – 1/2x = 15/2 -15

2x -3x/6 = -15/2

-x/6 = -15/2

x =15×6/2 =45 years

Q 2520) A rectangular piece of paper 22 cm x 4 cm is folded without overlapping to make a cylinder of height 4 cm. The volume of cylinder will be —

(A) 154 cm3   (B) 156 cm3   (C) 158 cm3   (D) 159 cm3

Ans: (A) 154 cm3

Solution:

In the question, length of the paper becomes the perimeter of the base of the cylinder and width becomes height.

Let the radius of the cylinder = r and height = h

Perimeter of the base of cylinder = 2πr = 22 cm

or  2πr = 2 x 22/7 x r = 22

Therefore, r = 7/2 cm

Volume of the cylinder = V = πr²h = 22/7 x 7/2 x 7/2 x 4 = 154 cm3

Other Questions

Q 2521) The internal measures of a cuboidal  room are 6 m x 4 m x 2 m. What will be the cost of whitewashing of all the four walls of the room, if the cost of white washing is Rs. 40 per m² ?

(A) Rs.1000      (B) Rs.1200      (C) Rs.1400      (D) Rs.1600

Ans: (D) Rs.1600

Solution:

Let the length of the room = l =6 m, width = b =4 m and height =h =2 m.

Area of the four walls of the room = Perimeter of the base x Height of the room

= 2 (l + b) x h = 2 (6 + 4) x 2 = 40 m²

Cost of white washing = 40 x 40  = Rs.1600

Q 2522) The given adjacent figure ABCD is a parallelogram. The ∠z is–

(A) 20°       (B) 25°       (C) 30°       (D) 35°

Ans: (C) 30°

Solution: In the adjacent figure, DC II AB, cut by transversal CA.

Then, y =40° , Because, pair of alternate angles are equal.

In ∆CBA, 70° = ∠y + ∠z (Exterior angle property)

70° = 40°+ ∠z

∠z =70° – 40° = 30°
