Question

what is unitary method

Answer 1

Unitary method is a mathematical term which is used to do solve questions for one single unit.

Say for example : we have to find cost of 10g of salt.If the cost of 5g is 60rs.

Cost of 5g of salt = 60rs.
then,
cost of 1g of salt =60/5
=12rs.
so,
cost of 10g of salt = 12*10
=120rs.
