Answer»

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
