Answer 1

Answer:

500 liter

Step-by-step explanation:

Solution:

Let the whole quantity be x in the given question:

(a) 5% of x = 600 \Rightarrow\ \frac{5}{100}\times x=600⇒

100

5

×x=600

\Rightarrow\ x=\frac{600\times100}{5}=12000⇒ x=

5

600×100

=12000

(b) 12% of x= Rs. 1080 \Rightarrow\ \frac{12}{100}\times x=1080⇒

100

12

×x=1080

\Rightarrow\ x=\frac{1080\times100}{12}=Rs.\ 9000⇒ x=

12

1080×100

=Rs. 9000

(c) 40% of x = 500 km \Rightarrow\ \frac{40}{100}\times x=500⇒

100

40

×x=500

\Rightarrow\ x=\frac{500\times100}{40}=1250\ km⇒ x=

40

500×100

=1250 km

(d) 70% of x = 14 minutes \Rightarrow\ \frac{70}{100}\times x=14⇒

100

70

×x=14

\Rightarrow\ x=\frac{14\times100}{70}=20\⇒ x=

70

14×100

=20 minutes

(e) 8% of x = 40 liters \Rightarrow\ \frac{8}{100}\times x=40⇒

100

8

×x=40

\Rightarrow\ x=\frac{40\times100}{8}=500⇒ x=

8

40×100

=500 liters.
