Answers
Step-by-step explanation:
____________________
Let the -
a number of targets he hit are x.
Given that a total number of targets are 100.
→ Hit targets = x
→ Missed target = 100 - x
Now,
He got Rs. 1 when he hit the target. But at the same time he losses Rs. 1 too, whenever he miss the target.
→ Hit target = 1(x)
= Rs. x
→ Missed target = 1(100 - x)
= 100 - x
Now, we have -
Rupees gain by man = Rs. x
Rupees loss by man = Rs. (100 - x)
The total amount of rupees (money) he got = Rs. 30
Rupees gain by man - Rupees loss by man = Received rupees
According to question,
x - (100 - x) = 30
x - 100 + x = 30
2x = 30 + 100
2x = 130
x = 65
•°• He hit the target 65 times.
Step-by-step explanation:
he answered 16 that's 16×4=64
now he missed 3 of them that's 3×2=6
now,
64-6= 58
therefore he got 58 rupees
