Question

350 kg is equal to 15 rupees so 1 kg equals to how many rupees.​

Answer 1

We know that 1kg=1000gm.

It is given that the cost of 1kg sugar is Rs.18 which means that the cost of 1000g sugar is Rs.18 then cost of one gram sugar will be:

1000

18

​  

=0.018

Therefore, 1gm sugar costs Rs.0.018.

Now, the cost of 250gms of sugar will be as follows:

Cost×number of grams=0.018×250=4.5

Hence, the cost of 250gms of sugar is Rs.4.5.

Answer 2

Explanation:

350kg - ₹15

1kg - ₹x

(Let's forget about the signs)

15*1kg = 350*x

15 = 350x

x = 15/350

x = 0.04

Therefore, x = 4 paisa
