Find the values of P and Q respectively.
The common difference between each consecutive term is 1400.
So P =10200+1400 = 11600
Q = 13000+1400 = 14400
12 friends met at a party. Each friend shook hands with each other exactly once. Number of handshakes took place is _____.
The first person shook hands with 11 remaining people, the second person also shook hands with 11 people, but we count 10, as the hand shake with the first person has already been counted.
Then add 9 for the third person, 8 for the fourth one & proceeding in this fashion
We get: 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 66.

The perimeter of the star equals the perimeter of the hexagon (all sides are equal). If each side of the hexagon is 20 cm long, then each side of the star is ____.
Perimeter is the sum of all boundaries of a figure.
Hexagon has 6 sides so permieter will be 6 x side length = 6x20 = 120 cm
Now since star and hexagon have same perimeter, Star has 10 sides
so perimeter will be
10 x side length = 120
side length = 120/10 = 12cm
If = 120 and = 100, then
Circle * Circle = 100
Let Circle = y
y * y = 100
y2 = 100
y = 10
Triangle + Triangle + Circle = 120
Let Triangle = x
x + x + 10 = 120
2x = 110
x = 55
Therefore, Triangle - Circle
= 55 - 10 = 45
Find the value of Y to make the expression true. 8000 = 50 × 80 × Y

There are 200 people in a hall. They are divided equally into 7 groups of adults and 3 groups of children. If there are 2 adults in each group, then how many children are there in each group ?
The correct answer is d
Let adult number be A and children number be C
7A + 3C = 200……Eq..1
7 × 2 + 3C = 200.. Eq..2
14 + 3C = 200
3C = 200 - 14
3C = 186
C = 186/3
C = 62
There are 62 children in each of the 3 groups

In a grazing field there are 60 goats, 30 deers and 10 children. How many legs are there in the field?
Goats and deers have 4 legs each. So number of legs of all goats and deers is
60+30 =90 x 4 = 360
and children (human) have 2 legs each, so
10 x 2 = 20 legs
total number of legs = 360+20 = 380
