Answer:
165
Step-by-step explanation:
Let x be the maximum score in the examination,
Since, first student gets 25% marks,
So, his/her score = 25% of x = 0.25x
Also, it is less than 40 marks from the minimum passing score,
Thus, the minimum passing score = 0.25x + 40,
Now, second student gets 60% marks,
So, his/her marks = 60% of x = 0.60x,
Also, it is more than 135 marks from the minimum passing score,
Thus, the minimum passing score = 0.60x - 135,
⇒ 0.25x + 40 = 0.60x - 135
⇒ 0.25x - 0.60x = - 135 - 40
⇒ - 0.35x = -175
⇒ x = 500
Hence, the minimum passing score = 0.25(500) + 40 = 125 + 40 = 165
