Soory Sorry I am late as I have a bunch of things to do. I’ll try to to do it right now :)
Q.1ans: $25 (c)
80% + 100% = $45
100% = ( 45/180 ) * 100
= $25
Q.2 ans: $60 (a)
10% * 40 = $4
100% = 5 * $4 = $20
$20 + $40 = $60
Q.3 ans: 7 : 60 (e)
Q.4 ans: 30% (b)
80 - 56 = 24
24/80 * 100
= 30%
Q.5 $60 (d)
100% + 20% = 120%
100% – 20% = 80%
100% + 120% + 80%
= 300%
300% = $450
1% = $1.50
( $1.50 * 80 )
= $120
( $1.50 * 120 )
= $180
$180 - $120 = $60

6 + 6 = 12
12 / 3 = 4
