2. 22.5 m can be bought from 675

Step-by-step explanation:

we will use unitary method in both of the question

1. since

15m=450 Rs ( cost of 15 m is 450)

40m = x Rs

x = 1200 Rs

2.

15m costs = 450 Rs

y m costs = 675 Rs

y = 22.5 m

Answer 2

Given data : Haseena buys 15 m of cloth for Rs 450.

To find :

• The cost of 40 m cloth ?
• How much cloth can she buy in Rs 675 ?

Solution : Now, we need to find cost of one metre cloth.

⟹ cost of one metre cloth

= 450/15

⟹ cost of one metre cloth

= Rs 30

Now,

⟹ cost of 40 metre cloth

= Rs {40 * 30}

⟹ cost of 40 metre cloth

= Rs 1200

Now,

⟹ Cloth purchase by Haseena in Rs 675

= 675/30

⟹ Cloth purchase by Haseena in Rs 675

= 45/2

⟹ Cloth purchase by Haseena in Rs 675

= 22.5 metre

Answer : The cost of 15 metre cloth is Rs 1200 and cloth purchase by Haseena in Rs 675 is 22.5 metre long.
