### Important Terms about Class 8 Maths Chapter 7

### A man got 10% increase in his salary. If his new salary is ₹1,54,000, find his original salary.

Let original salary be ₹ 100.

Therefore New salary i.e., 10% increase = 100 + 10 = ₹ 110

New salary is ₹ 110, when original salary = ₹ 100

New salary is ₹ 1, when original salary = 100/110

New salary is ₹ 1,54,000, when original salary

= [100/110] x 154000

= ₹ 1,40,000

Hence original salary is ₹ 1,40,000.

### On Sunday 845 people went to the Zoo. On Monday only 169 people went. What is the percent decrease in the people visiting the Zoo on Monday?

On Sunday, people went to the Zoo = 845

On Monday, people went to the Zoo = 169

Number of decrease in the people = 845 – 169 = 676

Decrease percent = [676/845] x 100 = 80%

Hence decrease in the people visiting the Zoo is 80%.
