Question

35% of the students of school are boys which is 259. (i) find the total number of students in school (ii) find the number of girls

Answer 1

Answer:

Step-by-step explanation:

Let total students are "a".

    If 35% are boys, then, 100% - 35% = 65% must be the % of girls.

In question,

⇒ 35% of total students = 259

⇒ (35/100) of a = 259

⇒ a = 259 * (100/35)

⇒ a = 740

          Hence,

(i): total students = 740

(ii): girls = 65% of 740

            = (65/100) * 740

            = 481

Answer 2

Step-by-step explanation:

Let the total no.of students be x.

Total no.of boys = 259

35% of x = 259

35x/100 = 259

35x = 259*100

35x  = 25900

x= 25900/35

x = 740

Thus, the total no.of students = 740

The total no.of girls = Total no.of students-Total no.of boys

                                 = 740 - 259

The total no.of girls = 481
