Question

A students scoref 36% marks then he is failed by 32 marks .But when he score 48% marks he is passed by 64 marks. Find passing % and maximum marks ?

Answer 1

40% is the passing %

and 800 is the maximum marks

Answer 2

hey mate here is your answer"""""'"'''

solution:let the maximum mark=x

so actual mark =x×36/100

passing mark =x36/100 +32

48% in number =x×48/100

then passing mark =x48/100-64

so,according to question,

x36/100+32=x48/100-64

x36/100-x48/100=-32-64

by taking LCM,

x36-x48/100=-96

-12x/100=-96

minus , minus are cancel,

12x=96

x12=96×100

x=96×100/12

x=8×100

x=800

then passing mark ,

x36/100+32

800×36/100+32

8×36+32

288+32

320

and passing percentage,

320/800×100

=320/8

=40%

so, there maximum mark=800

and passing percentage=40%
