Answer:

27

from the explanation,

let the number of maths that can be solved in 42 minutes = X

16 maths--------------25minutes

x maths --------------42 minutes

cross multiplying

X×25= 16×42

dividing bothsides by 25

25X/25 = 16×42/25

X = 672/25

X = 26.88 = 27 (approximately)

therefore 27 problems can be solved in 42 minutes
