Question

​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

Let’s take correct aims to be ‘a’, fails be ‘f’. Here, f=3.

Therefore, as per the problem statement,

total attempts=a+f=8, thus, a=8–3=5.

so, final amount= (2*a)-(0.5*f)

or, final amount=(2*5)-(3*0.5) =10–1.5 =8.5

Therefore, the final amount that he would get is Rs. 8.50.
