Answers
Answer:
Number of verbal questions = 30
Time taken for verbal question = 25 seconds
Number of maths questions = 40
Time taken to complete math question = 100 seconds
∴The total time she should allow for the test :
(30×25) + (40×100)
⇒750 + 4000
⇒4750 seconds
⇒ 79 minutes 10 seconds
⇒ 1 hour 19 minutes and 10 seconds
Answer:
→ Given Question:-
→ A teacher wants to make a test containing 30 verbal and 40 math questions. Each verbal question is to be allotted 25 seconds to complete and each math question is to be given 1 min 40 seconds. how many minutes should she allow for the whole test?
→ Solution:-
⇒ Time allotted for one verbal question = 25 seconds
⇒ ∴ Time for 30 verbal questions = 30 × 25 seconds
= 750seconds
⇒ Time allotted for one math question=1 min 40 seconds
= 1 × 60 + 40
= 60 + 40
= 100seconds
⇒ ∴ Time for 40 maths question = 40 × 100 = 4000
⇒ Total time for whole test = 100 + 750 = 850 sec
⇒ ∵ 60 sec = 1 min
⇒ ∴ 850 sec = 850 ÷ 60 = 14.1666666...min
