Question

a
packets of peanuts, each weighing
and by how much?

3.5 m of the same cloth.
​

Answer 1

Given

8.75m of cloth costs Rs 420

Can be written as

8.75 × 1 m = 420

1m = 42000/875

1m = Rs /- 48

Now Question says " find the cost of 3.5 m of the same cloth "

we will have to multiply it only

cost of 3.5 m = 3.5 × 48

= ( 7/2 ) × 48

= 24 × 7

= Rs /- 168
