the percentage of students who like grape juice=100%-(60+30)%=(100-90)%=10%

no. of people who like orange juice=
$60\% \: of \: 2500 \\ = \frac{60}{100} \times 2500 = 1500$

no. of people who like mango juice=
$30\% \: of \: 2500 \\ = \frac{30}{100} \times 2500 = 750$

no. of people who like grape juice=
$10\% \: of \: 2500 \\ = \frac{10}{100} \times 2500 = 250$

Answer 2

Step-by-step explanation:

The population of a city increase by 10% each year

Now,the present population of the town is 65000

After 1 year, the present population of the country will increase by 10%

10%of 65000

10/100×65000

6500

After incresing by 10%, the population is

= 65000+65000 × 10%

= 65000 + 65000 × 10/100

= 65000+6500

= 71500

so, After 1 year , the population of the city will be 71500

After 2 year later, the population of the city wil be increase by 10% of 71500

= 10%of 71500

= 10/100× 71500

= 71500

After increasing by 1p%1he population is

= 71500 + 71500 × 10%

=71500 + 71500 ×10/100

= 71500 + 7150

= 78650

Hence, After 2 year, the population of the city will be 78650
