91. Every time Deepa hits the target, she gets one rupee and every time she misses the target, she has to pay one rupee. She is allowed to try 100 times and gets an amount of Rs. 30. How many times did she hit the target?
(A) 35
(B) 65
(C) 80
(D) 75
Answer:
(B) 65
Explanation:
Let $x$ be the number of hits and $y$ be the misses. The total attempts are $x + y = 100$. The monetary result is $1(x) – 1(y) = 30$. Adding the two equations together: $2x = 130$. Solving for $x$ gives $x = 65$ hits.
