Father is 5 yrs older than the mother and the mother's age now is thrice the age of the daugther. The daughter is now 10 yrs old. What was the father's age when the daughter was born?
⇒ Mother's age = 3x
⇒ Father's age = 3x + 5
According to question,
x = 10
⇒ Father's age = 3(10) + 5 = 35 years
But, when daughter was born
Father's age = (35 - 10) years = 25 years
= √ (2722 - 1282)
= √( 73984 - 16384)
= √ 57600
= 240

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

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 cubes in fig. (II) and (IV) have the shaded face adjacent to the face bearing a square.
Hence, the cubes in these two fig. can't be formed.
Therefore, only cubes in fig. (I) and (III) can't be formed
