(i) The decrease in price is 280-210=70

Percentage of decrease 
=\frac{70}{280}\times 100
= 25%

(ii) increase of mark is 30-20=10

 Percentage of increase
=\frac{10}{30}\times 100
= 33.33%

Manish's Solution of Q 2 is wrong

Right answer is 50%

Original Marks - 20

Increased Marks - 30

Difference - 30-20 = 10

So now increased percentage = 10/20*100= 50%
