Question

a compositor takes 1 hour 45 min to compose 24 page of a book. how long will be take to compose 64 pages

Answer 1

1 h 45 min = 60 min + 45 min = 105 min

24 / 105 = 64 / x Muultiply both sides bx x

24 x / 105 = 64 Multiply both sides by 105

24 x = 64 * 105

24 x = 6720 Divide both sides by 24

x = 6720 / 24 = 280 min

x = 240 min + 40 min = 4 * 60 min + 40 min = 4 h 40 min


OR

64 / 24 = 8 * 8 / ( 8 * 3 ) = 8 / 3

( 8 / 3 ) * 105 = 8 * 105 / 3 = 840 / 3 = 280 min = 4 h 40 min
