A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of the son is :
Then, man's present age = (x + 24) years
∴ (x + 24) + 2 = 2(x + 2)
⇒ x + 26 = 2x + 4
⇒ x = 22
Three math classes : X, Y and Z take an algebra test
1. The average score of class X is 83
2. The average score of class Y is 76.
3. The average score of class Z is 85.
4. Average score of class X and Y is 79.
5. Average score of class Y and Z is 81.
What is the average score of classes X, Y, Z?
Let the number of students in class x, y & z be a, b and c respectively
Then,
Total of x = 83 a
Total of y = 76 b
Total of z = 85 c
And,
9x + 7y = 300 .....(i)
6x + 13y = 300 .....(ii)
Solving (i) & (ii) we get
y = 12 & x = 24
Then, x = 2 (y - 8)
or x = 2y - 16
again, x = y
or 2y - 16 = y
or y = 16
Total Number of boys & girls are 32
Area of a square field is 1 hectare. The length of another square field is 1% more than the length of this square field. The difference in their areas is
1 hectare = 10000 m2
Area of a square field = 10000 m2
let length of a square field be x m
then x2 = 10000
x = 100m
length of other square field = 100 + 100 x 1/100 = 101
Area of Another square field = (101)2 = 10201 m2
∴ Difference in their areas = 10201 - 10000
= 201 m2
A circular running path is 726 metres in circumference. Two men start from the same point and walk in opposite directions at the speed of 3.75 km. per hour and 4.5 km per hour respectively. Then when will they meet for first chance:
The two men walk in opposite directions @ 62.5 metres/minute and 75 metres/minute respectively
∴ They will meet for the first time after
AB and CD are two straight lines. Transversal EF intersects them as shown in the given figure. If b = c then
Clearly x + y = 180°
Two villages are 2 km apart.If the angles of depression of these villages when observed from a plane are found to be 45°and 60° respectively,then the height of the plane is
If x% of y is equal to z, what percent of z is x?

Above graph shows the percentage growth in population in six states A, B, C, D, E, and F from 1994 to 1995 and 1995 to 1996. Study the graph and answer their questions.
Q. Population of State 'F' in 1995 was approximately what percent of its population in 1996 ?
= 66.66%
≈67%
[Let population in 1995 be 100 then population in 1996 is 150]
Above graph shows the percentage growth in population in six states A, B, C, D, E, and F from 1994 to 1995 and 1995 to 1996. Study the graph and answer their questions.
Q. If the population of State 'B' in the year 1994 was 5 lakh, what was approximately its population in the year 1996?
Population of B in 1996 = 5 × 1.55 × 1.35 lakh = 10.4625 lakhs
≈10.5 lakhs
Above graph shows the percentage growth in population in six states A, B, C, D, E, and F from 1994 to 1995 and 1995 to 1996. Study the graph and answer their questions.
Q. If the population of States C and D in 1995 are in the ratio 2 : 3 respectively and the population of State 'C' in 1994 was 2.5 lakhs, what was the population of State D in 1995 ?
Popualtion of C : Population of D = 2 : 3
Hence Population of D in 1994
= 3.75 × = 6 lakh
Population of D in 1995 = 3.75 lakhs
Above graph shows the percentage growth in population in six states A, B, C, D, E, and F from 1994 to 1995 and 1995 to 1996. Study the graph and answer their questions.
Q. In 1994 the population of States B and D are equal and the population of State B in 1996 is 20.925 lakhs. What approx. was the population of State 'D' in 1996 ?
Let population of B in 1994 be x
Then x × 1.55 × 1.35 = 20.925 lakhs
⇒ x = 10 lakhs
As in 1994, population of D = Population of B Hence Population of D in 1994 is 10 lakhs Population of D in 1996 is = 10 × 1.6 × 1.7 lakh = 27.2 lakh
≈27 lakhs
