Question

the result of a number, when increased by 15%, is 161. find the number ​

Answer 1

Step-by-step explanation:

Let the original number = x

Increased percentage = 15%

Increased value = 161

Original value ( 100 + increased percentage)/ 100 = increased value

x {( 100+15)/100} = 161

x × ( 115 /100 ) = 161

x = ( 161 × 100) /115

x = ( 23× 7 × 5 × 20 ) / ( 23×5)

After cancellation

x = 140

Therefore , the original value of x = 140
