Question

which when increased by 10% become 66​

Answer 1

Answer:

The number is 60

Step-by-step explanation:

Let the number be x

10 % x = x × 10 / 100

10 % x = x / 10

Increasing the number by 10 %

10x + x / 10

11 x / 10

ACCORDING TO THE QUESTION

11 x / 10 = 66

11 x = 66 × 10

11 x = 660

x = 660 / 11

Hence ;

x = 60
