Answer:
10) 25/100× 720= 180
11)%= 6/600×100= 1%
13)21/100×42 = 8.82
12)600×75/100= 450
so for 25% decrease= 600-450= 150
Answer:
10 - 180.
11 - 1%
12 - 150.
13 - 42 is 19.905213270142% of 211
Step-by-step explanation:
10 - 25% of 720
implies,
25/100 × 720
= (25×720)/100
= 18000/100
= 180
11 - As 1 Rupee =100 paise
therefore, 1 paise = 1/100 rupee
then, we can write 6 rupees as 600 paises.
then, 6 paise = 6/600 rupees
=6/600×100
=6/6= 1%
12 - 600 x 25/100
= 150.
13 - To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 211 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 211, so we can write it down as 100%=211.
4. We know, that x% equals 42 of the output value, so we can write it down as x%=42.
5. Now we have two simple equations:
1) 100%=211
2) x%=42
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=211/42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 42 is what percent of 211
100%/x%=211/42
(100/x)*x=(211/42)*x - we multiply both sides of the equation by x
100=5.0238095238095*x - we divide both sides of the equation by (5.0238095238095) to get x
100/5.0238095238095=x
19.905213270142=x
x=19.905213270142
