Answer 2

Hi there!
Here's the answer:

°•°•°•°•°•°•<><><>\\\\\\<><><>°•°•°•°•°•°

Let the Number be x
& x decreased by 15% of x equals 170

=> x -15% of x = 170
[°•° x= 100%]

=> 85% of x = 170

{We have
x% of y = (x × y)/ 100}

=> (85×x)/100 = 170
=> 85x= 170×100
=> x= 200.

•°• The required Number is 200.

°•°•°•°•°•°•<><><>\\\\\\<><><>°•°•°•°•°•°

In short:
-15%x => 170
=> 85%x=170
=> x= (170×100)/85 =200

°•°•°•°•°•°•<><><>\\\\\\<><><>°•°•°•°•°•°

Verification:
The no. is 200.
100% = 200
=> 1%= 2
=> 15%= 15×2=30

200 -30 =170
Given Data Matched.
