Question

a candidate who scored 30% fails by 5 marks while another candidate who scored 40% marks geats 10 more than minimum pass marks what are the minimum pass marks required to pass?​

Answer 1

Answer:

. Let the total markbe x

Xx30/100+5 = Xx40 /loo-10

30x loo=40x/100-15

multiply by loo

30x=40x-I500

40x-30x=1500

lox=1500

x = 15oo/10=150

Total marks=150

minimum for pass=l 50x30/100+5 = 45+5=50. OR

150x40 / 100-1=60-10=50
