Answer:
The final amount after decreasing upto 2 DP is 771.18
Step-by-step explanation:
Amount given is 943
13% of ammount will be = 943 x 13%
=
Decreasing 13% from 943 we get = 943-122.59
=820.41
Now the ammount = 820.41
for finding 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
