Answer:
He scored 10 marks in his first test
Step-by-step explanation:
let the marks is first test be = ‘x’
then marks in 2nd test = x+10
Now according to statement
.... 5(x+10)=x^2
..... 5x+50=x^2
0=x^2-5x-50
By solving the eqn.
x^2-10x+5x-50=0
x(x-10)+5(x-10)=0
... either (x-10)=0 or (x+5)=0
x=10 ........ or x=-5 (rejected(
therefore answer is 10. Beacause marks can't be in negative.......so -5 is rejected
