Question

What was the price before £78 with 35% off

Answer 1

Price before £78 with 35% off is £120

Explanation:

Let the before price be 'x'.

According to the question 35% off on 'x' amount is £78

`\therefore \\ \rm \implies x - \bigg(x * (35)/(100) \bigg) = 78 \\ \\ \rm \implies x - (35x)/(100) = 78 \\ \\ \rm \implies (100x - 35x)/(100) = 78 \\ \\ \rm \implies 65x = 78 * 100 \\ \\ \rm \implies 65x = 7800 \\ \\ \rm \implies x = (7800)/(65) \\ \\ \rm \implies x = 120`
