Question:-

▪︎A boy gets Rs. 2 for every 5 correct aims at a target and loses Rs. 0.50 for every aim missed. In a game of 8 trials he missed the aim 3 times. How much amount does he get?

Answer:-

Given:

▪︎Total number of trial games = 8

▪︎Number of missed aims = 3

▪︎Rupees for correct aim = Rs.2

▪︎Rupees for missing aim = -Rs.0.50

To Find:

▪︎Total amount he get at the end of game.

Solution:

Number of times he got correct aim = 5 times

Amount he got for 5 correct aim = 5×2 = Rs.10

Amount he lost in 3 incorrect aims = 3×0.50 = Rs.1.50

Hence, total amount he hot at the end of games;

= 10-1.50

= Rs.8.50

Answer 2

$\huge\bf\fbox\red{Answer:-}$

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.
