Answer 1

answer:

1) 375 + 375 × 4/100 = 375 + 15 = 390

2) 36 - 36 × 162/100 = 36 -  5832 = 5786

3) let the number = x

x + 10/100 × x = 66

x + 0.1x = 66

x ( 1.1) = 66

x = 66/1.1

x=6

4) let the number be x

x - x × 35/100 = 52

x = 52/0.65

x = 80

5) let the increment be x

3260 + 3260x/100 = 3749

x = 4900/3260

x = 15

price of fan is increased by 155.

6) let the decrement in salary be x

32500 - 32500x/100 = 29900

x = -2600/-325

x = 8

8% of salary is deducted.
