Question

In a particular school in a rural area, 80% of the students below 13 are enrolled. Out of them, 85% attend the school regularly. If 340 students are regular, how many students are there in the area who are below 13​

Answer 1

Answer:

500 students

Step-by-step explanation:

Let total students below 13 are 100.

100 (Students below 13)  

(80% of them )  

80 (enrolled)  

85% of 80  

68 (regular)

∴   Putting the values in proportion, we get 68 : 100  : :  340  :  x

∴   x =  340 × 100/68  = 500 students

Answer 2

Answer:

500

Step-by-step explanation:

Let total students below 13 years are 100

According to the question,

100 (student below 13 years)

80%of them =80 enrolled

85%of 80 = 85/100 x 80 = 68(regular)

so,that.putting the value in proportion

we get :-

68 : 100 :: 340 : x

=> x × 68 = 100 × 340

=> x = 100×340/68 =500. ans.
