and the rest are creepers. Find out the number of each type of plants.
3) If 80 is increased to 125, what is the increase percent?
4) Raman has to score a minimum 40% marks for passing the examination. He gets 178
marks and fails by 22 marks. Find the maximum marks.
5) It takes me 45 minutes to go to school and I spend 80% of the time travelling by bus.
How long does the bus journey last?

Answer 1

Heya...
Here is your answer ----


2) Total number of plants = 500

=> Trees = 35%
= 35/100 × 500
= 35 × 5
= 175 trees

=> Shrubs = 20%
= 20/100 × 500
= 20 × 5
= 100 shrubs

=> Herbs = 25%
= 25/100 × 500
= 25 × 5
= 125 herbs

=> Creepers = [100 - (35 + 20 + 25)]%
= (100 - 80)%
= 20%
= 20/100 × 500
= 20 × 5
= 100 creepers


3) Original number = 80
After increase = 125
Difference = 125 - 80
= 45

=> Increase% = Difference/Original number × 100
= 45/80 × 100
= 45/8 × 10
= 450/8
= 225/4
= 56.25%


4) Let maximum marks be x
Passing marks = 40% of x
= 2/5x

Passing marks = 178 + 22
= 200 marks

Ac/q

2/5x = 200
2x = 200 × 5
x = 200 × 5 / 2
x = 100 × 5
x = 500

Maximum marks are 500.


5) Time = 45 minutes
Travelling by bus = 80%
= 80/100 × 45
= 8/10 × 45
= 8 × 4.5
= 36
The bus journey lasted for 36 minutes.
