A typist takes 80 minutes to type 24 pages. How long will he take to type 87 pages​

Answer 1

This question can be solved by unitary method in which the amount of 1 unit is found and then multiplied by x units to get amount in x days.

Answer :

290 minutes or 4 hours 48 minutes

Time taken to type 24 Pages = 80 minutes

Time taken to type 1 page = $\dfrac{80}{24}$ minutes

Time taken to type 87 pages = $\dfrac{80}{24} \times 87$

$= \tt \dfrac{6960}{24}$

= 290 minutes

$= \tt \dfrac{290}{60} \: hours$

= 4.83 hours

= 4 hours and 48 minutes

Hence , the man will take 4 hours and 48 minutes to write 87 pages .
