18/90×100=20%

Answer 2

Answer:

6) 4% of 1 hr 15 min

1hr 15min = 75 minutes

=(4/100)×75= 3 minutes

7)let the % be x

therefore,

x/100 ×90 =18

or, x=18×100/90 =20%

8)% of income spent =72%

let the monthly income be x

72/100*x is the money spent by him monthly

therefore,

x-72/100x=6300

or, 28/100x=6300

or, x= 6300×100/28=22500

therefore,

monthly expenses= 72/100×22500

=16200/- (ans)
