Answer 1

10% of 600 = 60

9% of 600 = ? ... 11% of 600 = ?  

1% of 600 = ?

proof

60 ÷ 600 =

0.1 =

0.1 × 100/100 =

0.1 × 100% =

(0.1 × 100)% =

10%

Answer 2

Let the number be a as given in the question.

20% of a is :

20/100 × a = 0.2a

600% of a is :

600/100 × a = 6a

Now lets relate the two according to the information given in the question.

0.2a + 60 = 6a

6a - 0.2a = 60

5.8a = 60

a = 60/5.8

a = 10$\frac{10}{29}$
