Question

The cost of 5 litres of milk is 227.50.
(a) Find the cost of 3 litres of milk. (b) How much milk can be bought for Rs
364?​

Answer 1

$cost \: of \: 5l \: milk \: = \: rs. \: 227.50 \\ cost \: of \: 1l \: milk \: = \: rs. \: \frac{227.50}{5} \\ = rs. \: 45.50$

$cost \: of \: 1l \: milk \: = \: rs. \: 45.50 \\ therefore \\ cost \: of \: 3l \: milk \: = \: rs. \: 3 \times 45.50 \\ = rs. \: 136.50$

therefore,

cost of 3L of milk costs ₹136.50

$cost \: of \: 1l \: milk \: is \: rs.45.50 \\ therefore \\ milk \: brought \: for \: rs. \: 364 \: \\ = \frac{364}{45.50} \\ = 8l$

therefore,

8L of milk can be brought for ₹364
