Answer 2

( 3 ) =
65 km / hr = 12 hr
1 km / hr = 12 / 65
78 km / hr = 12 / 65 *78
= 14.4 hr

( 4 ) =
16 months = 210 days
1 month = 210/16 days
14 months = 210 / 16 *14
= 183.75 days

( 5 ) =
540 pages = 28 lines
1 page = 28 / 540 lines
360 pages = 28 / 540 *360
= 18.7

( 6 ) =
Rs 200 = 54 machines
Rs 1 = 54 / 200 machines
Rs 20 = 54 /200 *20
= 5.4
