Dear Student,

● Answer -

Cost price = 20000 Rs

● Explaination -

# Given -

Selling price = 24000 Rs

Profit % = 20 %

# Solution -

Selling price is related to cost price as -

Selling price = Cost price × (100+profit)/100

Rearranging the eqn -

Cost price = selling price × 100 / (100+profit)

Substitute values -

Cost price = 24000 × 100 / (100 + 20)

Cost price = 24000 × 100 / 120

Cost price = 20000 Rs

Hence, cost price of a TV is 20000 Rs.
