Question

a number is increased by 25% and then decreased by 20%.find the percentage change in the number?​

Answer 1

Answer:

Let the no. be 100

Since, it is increased by 25%

therefore,new no.=100+25% of 100-125

then, no. is decreased by 20%

so,new no. 125-20% of 125-125-25-100

So,the no. got is equal to the no.

100 = 100

therefore this no. is not decreased nor incresed
