Answer:
400$
Step-by-step explanation:
Let C.P. of the watch = Rs. 100
When profit =5%; S.P. = Rs. (100+5)
= Rs. 105
and when profit = 11%;
S.P. = Rs. (100+11)
=Rs.111
Difference of two selling prices
= Rs. 111-Rs.105 = Rs.6
When watch sold for Rs. 6 more; then C.P. of the watch = Rs.

When watch sold for Rs. 24 more; then C.P. of the watch = Rs.

The slope is -5/2.
since the slope is decreasing, it is negative.
Answer:
5 years
Step-by-step explanation:
We are given;
- Initial value of the car = $12,500
- Rate of Depreciation = 13% per year
- New value (after depreciation) = $6,250 (half the initial value)
We are required to determine the time taken for the value of the car to depreciate to half the original value.
- We need to know the depreciation formula;
- New value = Initial value ( 1 - r/100)^n
Therefore;
$6,250 = $12,500(1 - r/100)^n
0.5 = (1 - 13/100)^n
0.5 = 0.87^n
Introducing log on both sides;
log 0.5 = n log 0.87
Therefore;
n = log 0.5 ÷ log 0.87
= 4.977
= 5 years
Therefore, it takes 5 years for the value of the car to depreciate to half the initial value.
