Answer:
20
Step-by-step explanation:
1. You "cross-multiply" 120 to 5 (120*5).
2. You divide 600 (120*5=600) to 30, which is (600/30).
3. You get the answer which is 20.
18:162
1:9
1+9=10
(1×180)÷10= 18
(9×180)÷10=162
62.17
42.75 dollars more
57/4= 14.25
Gaurav has 14.25 dollars
57-14.25=42.75
therefore Deepa has 42.75 more dollars than Gaurav
