Question

find a number which when increased by 10% becomes 66.

Answer 1

Let the number = x

10 % of x = x × 10/100
=x/10

Increasing the number by 10% = 
x+x/10
= 11x/10

ATQ
11x/10 = 66
11x = 660
x = 60


Therefore number = 60


Hope this helps you..!:)

Answer 2

Step-by-step explanation:

• 10%=66

• x+10/100=66

• =x+10/100×X=66 (x: to find. X: 66)

• =x+10/100×66= 66

• =x+660/6600=60

• =x+ 1/10=66

• x= 66-10/1

x=60
