Q1:
150 pages is the answer
2 hours= 60+60minutes
So 120/40 =3
Answer= 50×3= 150.
Q2:
Using Work=men×days we get
Work=20×20
Work=400
Now, work is same and number of days are to be calculated
400=25×days
days= 16
400 = 25 x 16
so it will take 16 days

Please note that the symbols "/" and "÷" and the word "over" are generally taken to mean exactly the same thing.* When math operations are involved in numerators or denominators, generally you need to enclose those numerators and denominators in parentheses.
1/3÷4/7 = 1/(3·4·7) = 1/84
(1/3)÷(4/7) = (1/3)·(7/4) = 7/12
___
* Some web sites treat them differently. Sometimes "÷" is taken to mean "the quantity everything that comes before the symbol '÷' divided by the quantity everything that comes after the symbol".

Answer:
17.4 (3 Significant numbers)
Step-by-step explanation:
Formula for finding Cylinder : π r² h
So your 5453 = π x (20cm ÷ 2)² x height
To get height (tallness), divide 5453 by (100π)
Depending on your π, your answer should be either, 17.366 / 17.35 / 17.357 which all rounds up to 17.4 if your question asks for 3 significant figures
