Answer 1

Given:

Some packets of sausages and rolls were brought.

To find:

Minimum number of packets of sausages and roll brought which cost same.

Solution:

1) The cost of sausage packets is ₹10.

The cost of roll packets is ₹15.

2) If we want to make the cost of both roll same then we have to take the LCM of 10,15

• LCM[10, 15] = 30

3) In ₹30 we can buy 3 packets of sausage and ₹30 we can buy 3 packets of roll.

Minimum 2 packets of sausage and 3 packets of roll can be bought in same cost.
