The written problem needs to be converted to mathematical expression. For this, we use the unknown variable for the things which need to be found out.
Explanation:-
Total chances = 100
Suppose, that the chances he misses = x
Thus, the chances he hits = (100 - x)
Now, total money he gets is 300. Chances need to hit on target to earn Rs. 300,
⇒ 300 / 10 = 30
Hence, the price and penalty is same. So, the difference of hits chances and missed chances will be 30 (remaining chances). Thus,
⇒ (100 - x) - x = 30
⇒ 100 - x - x= 30
⇒ -2x = 30 - 100
⇒ -2x = -70
⇒ x = 35
Since, the number of chances he missed is 35.
Hence, the correct option is 1.
