Explanation / Answer

21) Neither.

22) Neither.

25) Let P be the price of a large plain cheese pizza and t be the cost of each large pizza topping.

Then, by given conditions, we have,

P+2t = 14..........(i)

And, (P+t)*80% = 10

i.e., (P+t)*0.8 = 10

i.e., P+t = 10/0.8

i.e., P+t = 12.5..........(ii)

Subtracting (ii) from (i) we have,

(P+2t)-(P+t) = 14-12.5

i.e., t = 1.5

Putting this value in (ii) we get, P+1.5 = 12.5

i.e., P = 12.5-1.5

i.e., P = 11

Therefore, $11 is the price of a large plain cheese pizza and $1.5 is the cost of each large pizza topping.
