Question

23. A student was awarded certain marks in an
examination. However, after re-evaluation, his
marks were reduced by 40% of the marks that were
originally awarded to him so that the new score now
became 96. How many marks did the student lose
after re-evaluation?
a) 58
b) 68 c) 63
d) 56
e) 64​

Answer 1

Answer:

E is the answer

Step-by-step explanation:

Let the initial marks be x

Given he loses 40% implies

x-40÷100(x)=his new score

Given his new score is 96, using it in above equation

x-40÷100(x)=96

x-0.4x=96

0.6x=96

X=160

Therefore his original score was 160

Marks lost =original score - new score

Implies 160-96=64
