Answer 1

Answer:-

As per one clue card, the total number of children in the school is 60.

Solution:-

Number of births in January = 25%

$= \frac{25 * 60}{100}$

$= 15$

15 births in January

Number of births in February = 0 [given]

Number of births in spring {March, April, May} = 20%

$= \frac{20 * 60}{100}$

$= 12$

Births in March = 2 [Given]

Births in April = 2 + 3 [Given]

= 5

Births in May = 5 [Equal to April][Given]

Number of births in June = 5%

$= \frac{5 * 60}{100}$

$= 3$

Births in June = 3

Number of births in July = 10%

$= \frac{10 * 60}{100}$

$= 6$

Births in July = 6

Births in August = 0 [Given}

Births in September = 3 [Given]

Number of births in October = $\frac{1}{6}$ Of total

$= \frac{60}{6}$

$= 10$

Births in October = 10

To calculate the number of births in November, we will first calculate the births in December.

Number of births in December = 9 [Given]

Since no information is given regarding the births in November, we will us BODMAS rule to find this out.

Births in November = Total - Sum of rest of Births

= 60 - [15 + 2 + 5 + 5 + 3 + 6+ 3 + 10 + 9]

= 60 - 58

= 2

Births in November = 2
