Question

if a person required at list 2 pairs of gloves and 3 masks daily. the cost of this item is rupees 300. taking the cost of 1 pair of gloves as "P" and cost of 1mask as "Q" make an equation in two variable and draw the graph for the same​

Answer 1

Answer:

Let cost a pair of gloves =P

Cost of a mask = Q

ATQ

2P +3Q=300

Answer 2

Step-by-step explanation:

Given that:

if a person required at list 2 pairs of gloves and 3 masks daily. the cost of this item is rupees 300. taking the cost of 1 pair of gloves as "P" and cost of 1mask as "Q"

To find:

An equation in two variable and draw the graph

Solution:

As given in the question

Cost of 1 pair of gloves is rupees ='P'

So, Cost of 2 pair of gloves is rupees= 2P

Cost of 1 mask is rupees ='Q'

So, Cost of 3 masks is rupees= 3Q

ATQ,

Total cost of both the items are 300/-

So,

2P+3Q=300

Graph: Put different value of P to find different value of Q

Solution 1: Let P = 0

then 2(0)+3Q=300

3Q=300

Q=100

one point/solution (0,100)

2: Let Q=0

then 2P+3(0)=300

2P=300

P=150

Second point/solution (150,0)

mark these two points on the graph,and join with a straight line.

The line shows the graph of linear equation in two variables P and Q.

Hope it helps you.
