Step-by-step explanation:

SOLUTION:

Given, hari wants to buy equal number of oranges and apples.

The oranges are packed in a packet of 6 and the apples are packed in the packet of 10.

Now, let us find how many packets of each food she should buy?

Let the number of packs of oranges be x and number of packs of apples be y.

According to the given information,

6 × x = 10 × y

3x = 5y

Here, 3x is multiples of 3 and 5y is multiples of 5.

We know that, the least number which is common in 3 multiples and 5 multiples is 15.

So, 3x = 15 and 5y = 15 → x = 5 and y = 3.

So, Hari has to buy 5 packs of oranges and 3 packs of apples.

Now, let us find the least number of apples lali has to buy.

From above part, we came to know that, she has to buy atleast 3 packs of apples.

So, the least number of apples = 3 x 10 apples per pack = 30 apples.

Hence, hari has to buy 5 packs of oranges and 3 packs of apples with 30 apples as least count.
