Question

Suresh has 90 copies and he distributed 1/3 of the copies to 10th class students and the remaining 1/4 of the copies among the 9th class students. Rest of the copies he gave to the 8th class students how many copies he gave to the 8th class students

Answer 1

Given :

Total copies with Suresh : 90

Part of copies distributed to class 10 : ⅓

Part of copies distributed to class 9 : ¼

Rest of the copies were distributed to class 8th.

To find :

The number of copies distributed to class 8th.

Solution :

Number of copies given to class 10 :

$\sf \dashrightarrow \dfrac{1}{3} \: of \: 90$

$\sf \dashrightarrow \dfrac{1}{3} \times 90$

$\sf \dashrightarrow \dfrac{1 \times 90}{3} = \dfrac{90}{3}$

$\sf \dashrightarrow 30$

Now, let's find the number of remaining copies.

Remaining copies :

$\sf \dashrightarrow 90 - 30$

$\sf \dashrightarrow 60$

Number of copies given to class 9 :

$\sf \dashrightarrow \dfrac{1}{4} \: of \: 60$

$\sf \dashrightarrow \dfrac{1}{4} \times 60$

$\sf \dashrightarrow \dfrac{1 \times 60}{4} = \dfrac{60}{4}$

$\sf \dashrightarrow 15$

Now, let's find the number of remaining copies.

Remaining copies :

$\sf \dashrightarrow 60 - 15$

$\sf \dashrightarrow 45$

As he gave the rest of the copies to class 9th. The number of remaining copies are 45.

Hence, the number of copies given to class 8th are 45 copies.
