Given :

15 litre of mustard oil cost Rs 1700

To Find:

Solution:

$\\ 15 \: litre \: mustard \: oil = rs \: 1700 \\ \\ 1 \: litre \: mustard \: oil \: = \dfrac{1700 \times 1}{15} \\ \\ = 113.33 \: rs$

Required Answer:

Extra points:

Solve such question using unitary method

Example:

5 chocolate cost Rs 10

1 chocolate cost Rs x

1 × 10 = 5 × x

10/5 = x

2 = x

Therefore, 1 chocolate cost Rs 2

---> 1 bottle contain 5 beads

5 bottle contain x beads

5 × 5 = 1 × x

25/ 1 = x

25 = x

Therefore, 5 bottles contain 25 beads
