Question

By selling an exhaust fan for Rs. 1470, a man gains profit of 1/6 of its cost price. Find its cost price.​

Answer 1

₹245 is the cost

Explanation:

Given:

Cost of the fan = ₹1470

1/6th = 1470/1 × 1/6

(do not cross multiply and simplify)

= ₹245

Answer 2

Rs 1260

Explanation:

let x be the cost price , then

x +
`(1)/(6)` x = 1470 , that is

`(7)/(6)` x = 1470 ( multiply both sides by 6 to clear the fraction )

7x = 8820 ( divide both sides by 7 )

x = 1260

The cost price was Rs 1260
