Question

If number is increasing 10 percent after that increases 20 percent find final change

Answer 1

Answer:

32% increase

Step-by-step explanation:

Let the no. be n

when it increases by 10%, the change is

n + 10% of n

= n + 10/100 × n

= n + n/10

=10n +n /10

=11n/10

when the no. increases 20%,

11n/10 + 20% of 11n/10

=11n/10 + 20/100 × 11n/10

=11n/10 + 11n/50

=55n+11n / 50

=66n/50

change=66n/50 – n

=66n – 50n /50

=16n/50

change% = 16n/50 /n ×100

=16n/50n × 100

=32%

So there will be 32% increase in the no. finally
