Everytime 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 ?

Options

A. 35
B. 65
C. 80
D. 75

Answer

B

Explanation

Let the number of times deepa hits the target = x
Then, the number of times she misses the target = (100 - x).
According to the question,
`x-(100 – x) = 30 `
or, `x-100 + x = 30 `
or, `2x = 130 `
or, `x= 65 `
Therefore, required number of times deepa hits the target = x = 65.
