Size of a tile is 9 inches by 9 inches. The number of tiles needed to cover a floor of 12 feet by 12 feet is
Length of floor = 12 feet
Breath of floor = 12 feet
So Area of floor = 12 x12 = 144 feet
Area of tile = 9/12 x 9/12 = 9/16 feet
So the number of tile = 144 /9/16 = 256 tiles
The average annual income (in Rs.) of certain argicultural workers is S and that of other workers is T. The number of agricultural workers is 11 times that of other workers. Then the average monthly income (in Rs.) of all the workers is:
Let the number of other workers be x
Then, number of agricultural workers = 11x
Total number of workers = 12x
∴ Average monthly income
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is :
Tupstrean = 2.tdownstream
⇒ Speed up/Speed down = t + 1/t  1 = 3/1
⇒ 3 : 1
The difference between simple and Compound Interest on a sum of money for 2 yrs at 10% per annum is Rs 65. The sum is
Find the number of triangles and squares in the given figure.
Triangles:
The simplest triangles are JBO, BKO, KDO, DFO, FGO, GHO, HIO, IJO, ABJ, BCK, CKD and DEF i.e.12 in number.
The triangles composed of two components each are IBO, BDO, DGO, GIO, ABO, CDO, CBO, CBD and DEO i.e. 9 in number.
The triangles composed of four components each are IBD, BDG, DGI, GIB, ACO and COE i.e. 6 in number.
There is only one. triangle i.e. ACE composed of eight components.
Thus, there are 12 + 9 + 6 + 1 = 28 triangles in the given figure.
Squares:
The squares composed of two components each are BKOJ, KDFO, OFGH and JOHI i.e. 4 in number.
There is only one square i.e. CDOB composed of four components.
There is only one square i.e. BDGI composed of eight components.
Thus, there are 4 + 1 + 1 = 6 squares in the given figure.
The Speaker of the Lok Sabha has to address his letter of resignation to
The mass of a body on earth is 100 kg (acceleration due to gravity, ge = 10 m/s2). If the acceleration due to gravity on the moon is (ge/6), then the mass of the body on the moon is
An angle which is greater than 180^{o} but less than 360^{o} is called a/an :
In the first column, 3 x 100 + 5 x 9 = 345.
In the second column, 4 x 100 + 6 x 10 = 460.
∴ In the third column, missing number = 5 x 100 + 7 x 11 = 577.

Rs. 8840 is divided between x and y in such in such a manner that for every Rs. 6 that x gets, y gets Rs.7. Their shares are
x ′ s share = 6/13 x 8840 = R s . 4080.
y ′ s share = 7/13 x 8840 = R s . 4760.

If the areas of the three adjacent faces of a cuboidal box are 120 cm^{2}, 72 cm^{2} and 60 cm^{2} respectively, then find the volume of the box.
The sides of cuboidal box are √120 cm, √72 cm and √60 cm respectively.
The volume of a cuboidal box
= √120 x √72 x √60 cm^{3}
= 719.9999
≅ 720 cm^{3}
