Question

In a test, Calvin secured 40% marks and failed by 60 marks while Susie secured 60% marks
and passed by 40 marks. What is the passing percentage?​

Answer 1

Answer:

68%

Step-by-step explanation:

Let the maximum marks is x

According to the condition of the given question we can say that

(40% of x)+60 = (60%of x)-40

on solving

(40% of x) - (60% of x) = (-40–60)

-(20%of x) = -100

20% of x = 100

(x*20)/100 = 100

on solving x=500

chitra marks = (40% of x +60 +80)

where x =500

so on solving (500*40)/100 +140

= 340

so percentage = (340*100)/500

= 68%

Answer 2

Answer:

52%

is the passing percentage marks
