P+7/p-6 =1/3
3(p+7) = 1(p-6)
3p + 21 = p - 6
3p - p = -6 -21
2p = - 27
p = -27/2

15(y-4)-2(y-9)+5(y+6)=0
15y - 15(4) - 2y + 2(9) + 5y + 30 =0
15y - 60 - 2y + 18 + 5y + 30 =0
15y - 2y + 5y - 60 + 18 + 30 =0
18y - 42 + 30 =0
18y - 12=0
18y = 12
y = 12/18 = 6/9

1. If you subtract ½ from a number and multiply the result by ½, you get 1/8 what is the number?
Solution:
Let the number be x.
According to the question,
(x – 1/2) × ½ = 1/8
x/2 – ¼ = 1/8
x/2 = 1/8 + ¼
x/2 = 1/8 + 2/8
x/2 = (1+ 2)/8
x/2 = 3/8
x = (3/8) × 2
x = ¾
2. The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?
Solution:
Given that,
Perimeter of rectangular swimming pool = 154 m Let the breadth of rectangle be = x
According to the question,
Length of the rectangle = 2x + 2 We know that,
Perimeter = 2(length + breadth)
⇒ 2(2x + 2 + x) = 154 m
⇒ 2(3x + 2) = 154
⇒ 3x +2 = 154/2
⇒ 3x = 77 – 2
⇒ 3x = 75
⇒ x = 75/3
⇒ x = 25 m
Therefore, Breadth = x = 25 cm
Length = 2x + 2
= (2 × 25) + 2
= 50 + 2
= 52 m
3. The base of an isosceles triangle is 4/3 cm. The perimeter of the triangle is 
cm. What is the length of either of the remaining equal sides?
Solution:
Base of isosceles triangle = 4/3 cm
Perimeter of triangle =
image cm = 62/15
Let the length of equal sides of triangle be x.
According to the question,
4/3 + x + x = 62/15 cm
⇒ 2x = (62/15 – 4/3) cm
⇒ 2x = (62 – 20)/15 cm
⇒ 2x = 42/15 cm
⇒ x = (42/30) × (½)
⇒ x = 42/30 cm
⇒ x = 7/5 cm
The length of either of the remaining equal sides are 7/5 cm.

Following are the terms used in Probability.
- Random experiment - An experiment which can result in a set of possible outcomes. An outcome is the result of the experiment. Example, bowler bowling a ball in cricket. It can result in batsman hitting it, wicket, no-ball, wide etc.
- Event - Each outcome of an event or a collection of outcomes make an event. Example, tossing of coin results in getting a Head which is an event. Getting a tail is also an event.
- Equally likely outcomes - When the probability of all the outcomes in a random experiment is almost equal. Example, tossing of coin. It can either result in heads or tails, so the two outcomes are equally likely.
