Remember the divisibility rule for 9. The sum of the digits of the number must be divisible by nine. 
Let the digit be x. Then x+3+5+2+0=x+10 has to be divisible by nine. Recalling that 18=9*2, we note that x=8.

What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
kipiarov [429]

Answer:

771.18

Step-by-step explanation:

The Amount given is  943

13% of amount will be =  943 x 13%

                         =

Decreasing 13% from 943 we get = 943-122.59

                        =820.41

Now the ammount = 820.41

for finding the final amount

find 6% of amount (820.41) we get =  820.41x 6%

                               =

Decreasing 6% from 820.41 we get final amount= 820.41- 49.23

                                   =771.18

so the final amount is 771.18
